Light and sound are things that essentially almost every human being has access to to the experience. Light and sound have been observed since the 17th century and there is still even more to discover even today. Light has given us the opportunity to see around us and given advancements including the solar panels. Sound has also given us an opportunity to listen to noises around us like instead of always reading books now people can listen to them with Audiobooks, and people can also have speakers that can help with the intensity of the sound. Sound and light are combined in some cases similar a phone or a computer to give the light needed to see the screen and the sound to hear music and videos. Sound and light are diverse in numerous methods. …show more content…
First of all, what type of wave is light and sound? Light and sound are not the same types of wave. There are 2 types of waves and light is a transverse wave while sound is a longitudinal wave. Source D states, “Longitudinal waves are waves whose direction of vibration is the same as their direction of travel…. Transverse wave is a moving wave that consists of oscillations perpendicular to the direction of the energy transfer.” Suchlike proves that longitudinal and transverse are divergent types of waves. The author Chris Woodford hereto in the article, “ Sound waves are compression waves. They’re also called longitudinal waves…” (Source B pg. 2). Indeed, it proves that sound waves are longitudinal waves. Source A states, “ An electromagnetic wave is a transverse wave that involves the transfer of electric and magnetic energy” (69). Thus, as the text shows that light is transverse waves. Now it is time to see how sound and light …show more content…
Sound can reflect while light can refract, diffract and interfere as well, including reflecting Source C reads, “Light waves behave in 4 interesting and useful ways that we describe as reflection, refraction, diffraction, and interference” (2). As demonstrated, the article says that light can act or behave in 4 multifariously ways. The author states, “ What you hear is, of course, sound reflection, better known as an echo….” (Source B, 2) The base of the data tells that sound can be reflected but cannot be refracted, diffracted, or interfere. Sound and light also differ in how the wave travels. Light travels or acts similar to a wave or particle while sound travels with a medium.“ Like other mechanical waves, sound waves carry energy through a medium without moving the particles of the medium along” (Source A pg. 34) From cited corroboration, it shows that sound travels with a medium. From source A its allures, “It has many properties of waves, but can also act as though it is a stream of particles” (pg. 70). It tells that light can be a wave or a particle. Light and sound are heterogeneous and are also shown in what speed these waves travel at.
Speed is contrary to all types of mediums, and are unlike between sound and light. Sound travels slower than light. From source B the writer states, “The speed of sound in air (at sea level) is about 1120 km or 340 meters per second.” Such as told the speed of sound is around 1120
Throughout Canada, increasing use is being made of award winning Echo Sound Barriers to counteract noise pollution. As companies become aware of the advantages of the range of noise reduction solutions available from the Echo Barrier company, the impact of noise on the environment in Canada is reducing. This can only be an advantage to the health and welfare of the nation. Unacceptable levels of sound can come from many sources. Construction and building work, demolition sites, generators, airports and railways and even children playing in the garden can make life unbearable for those who live or work in close proximity.
This also causes for many different frequencies. The waves of an incoherent light are rampant and out of phase causing them to interfere with one another. On the other hand, a beam of light with the same frequency, phase, and direction is called a coherent light. In this form of light, there is no interference of waves within the beam, and only a beam of coherent light will not spread and diffuse.
The three most important properties of a wave are the wavelength, the amplitude, and the frequency. The wavelength is the distance from one point on a wave to the next identical point on the next wave. The amplitude is the distance from a waves rest position to either the crest or trough of the wave. The frequency is a rate which represents the amount of times a wave repeats
1. Identify the range of senses involved in communication • Sight (visual communication), Touch (tactile communication), Taste, Hearing (auditory communication), Smell (olfactory communication) 2. Identify the limited range of wavelengths and named parts of the electromagnetic spectrum detected by humans and compare this range with those of THREE other named vertebrates and TWO named invertebrates.

Wave properties: Frequency: How many waves go past a point in one second; measured in hertz (Hz). The higher the frequency, the more energy in the wave. 1 Ask the children to play 'verbal tennis' in partners on words that describe sounds (eg loud, quiet, vibration, pitch). One child says one word related to sound, then their partner says another and so on. 2 Ask the children what things make sounds.
Block diagram for sending two similar tones with a difference in frequency This generates the binaural beats. This is given to the ears. As the difference in these two waves is 10 Hz which is below 20 Hz, it is inaudible to the human ear. But there is a neuron called offer on neuron inside the ear which senses this 10 Hz and sends it to the brain as a stimulus.
In expertly writing his story centered around sound and silence, Brockmeier makes a statement of the issue of noise and it’s effects on the people who hear it by continuously describing them throughout the story. A hundred years ago, there didn’t exist the sounds that exist today; maybe one could stop and hear a bird whistle in a lightly rustling breeze while crunching on leaves as they would go for a walk. Now, especially in heavily urbanized areas, it is possible to hear all sorts of planes, trains, automobiles, rings and dings and all sorts of other things, and this was certainly the case in the beginning of the story when the very sounds themselves are described as “ [a] boom”, “scraping”, and “cutting through the air”, all of which are
An ultrasound technician also relies on sound waves to produce images of international organs, soft tissue, and blood vessels” (Inner Body). “Diagnostic
Just imagine, life with no sound. Weird right! Sounds are the little noises heard at night and during the day. They are minuscule.
The material world is the one we can see, touch, hear and smell, are just false truths of the reality. By relying just on your senses is making yourself blind from the real world. The world we see is a reflection of the forms the real world represents. By understanding these forms can lead to true
Sound is embodied in the black body whether it be in everyday conversation, intimate exchanges with a loved one, heart wrenching calls, or music rendered from the soul. Sound is essential to living beings as both a primary and secondary sense used to interact with the world. Sound enables communication. Communication creates community. Community leads to emotional connections and understanding.
A: Snell’s law allows us to work out the index of refraction of light through an object. We can use this and insert into a formulae of “n=c/v. We know that the speed of light is about 300,000 kilometres per second so if we add this into the formulae as well as the index of refraction we can work out the speed of light travelling through the
The rate at which acoustic waves travel depend on eruption size. As acoustic waves hit the ground, they become ground waves “that shake a seismometer much like earthquake waves do.” Though scientists have observed and disregarded the transition of acoustic waves into ground waves, David Fee, a seismologist at the University of Alaska Fairbanks, decided to study acoustic waves using seismic data from the Veniaminof and Pavlof volcanoes. The article stated how Fee and his team adjusted their data knowing acoustic waves traveled ten times slower than seismic waves. They extracted acoustic waves from seismic data.
As light travels through different materials, it scatters off of the molecules in the material and slows down. Nothing ever travels faster than c in vacuum, however, for different mediums, this is not the case. In materials such as water, light will slow down more than electrons will. Thus an electron in water can travel faster than light in water. The amount by which light slows in a given material is described by the index of refraction, or in other words, n.
Open-open had .647m and the open-closed had .630m of distance. The tube with the least percent error and closest to the actual speed of sound was the open-open tube with a frequency of 512
