What is a Refractor telescope? A refracting telescope is a type of optical telescope, that magnifies objects from far away. It does this by refracting the light rays it collects to create an image that is inverted and thus magnified. There are many different types of telescopes but most have the same parts to them. Refracting telescopes have two convex lenses: The Objective lense - this lense has a greater diameter than the second lense as the greater the aperture, the more light it can collect and bring into focus at the focal point.
Title of investigation: To investigate the factors which affect the refraction. Research question: To investigate how the different mediums affect the refractive index. Background: The refraction of light is the wave bending while it travels to the medium with different speed. The refractive index is a ratio between the speed of light in the medium and the speed of light in vacuum or in the air. The Snell`s law states that going into the denser medium, light slows down and bends toward the normal line, and going into the less denser material, light seeds up and bends away from the normal line.
1.5 Diamond 2.4 On a light ray, the angle of incidence will help determine the angle of refraction. There is a intercept point as shown below where the two mediums and the normal meet. The angle between the incidence ray and the normal is the angle of incidence and the angle between the ray of refraction and the normal is the angle of refraction. Rays that travel into less dense areas than originally (Index of refraction decreases) will cause the angle of refraction to be greater than the angle of incidence, making it refract away from the normal. Rays that travel into more dense areas than originally (Index of refraction decreases) will cause the angle of refraction to be less than the angle of incidence, making it refract towards the
It can be positive or negative for the orders of diffraction depending entirely on the selected sign convention. From the equation above, the greater the discrete wavelength of the diffracted light, the maximum the diffracted light will have at angle of diffraction. Figure 7: Geometry of diffraction grating As for the non-normal incidence case, if a plane wave is incident at any arbitrary angle, and the beam of light strikes the grating at angle of θ1 relative to the angle of θ, the grating equation will be shown as follow d(sinθ1+sinθ)=mλ This equation is applied independently of the surface refraction
The strings should have a huge amount of energy but physicists worked out that vacuum energy could cancel with vibrational energy, lowering the string’s overall energy and mass. This allows vibrating strings to appear as massless or nearly massless particles. Using string theory, it can theorise the massless particle with all the properties of the graviton. This is important because not many theories can support the idea of the
This then lead to the conclusion that light is a wave because as the light went through the slits and onto the screen, the light beams interfered with each other as there were dark and light beams on the page, meaning that where the crests met, the light was bright and where a crest and trough met the light was darker as crests and troughs cancel each other out. (William Harris and Craig Freudenrich, n.d.) It was the concluded that light must be a wave as it shows the properties of waves. The particle theory of light It was first hypothesised by Isaac Newton that light consisted of a lot of small particles which were emitted in all directions from a source, such as metal. Albert Einstein believed that light was composed of tiny particles called photons, and each photon has energy, after studying the photoelectric
Student’s Name Institution Course Name Professor’s Name Date of Submission Optics: Reflection and Refraction and Lab Report Introduction The objective of this experiment was to analyze the laws of reflection and refraction. In this experiment, the relationship between the angle of reflection, the angle of refraction, and the angle of incidence was established. If a line is normal to the surface at the point where the light beam strikes the surface, then the reflected angle is equal to the angle of incidence as shown in figure 1. It is important to note that these angles are measured relative to the normal. Figure 1: Reflection and Refraction of Light Refraction occurs when part of the beam of light incident to a surface bends as it
When light is scattered by matter in such a manner that there is no change in the energy in the scattered wave (elastic), the scattering is termed as Rayleigh scattering. When the scattering is inelastic, thereby resulting into a scattered light with different energy from incident light, the scattering is referred to as Raman scattering. The aforesaid phenomenon was experimentally observed for the first time by Chandrasekhara Venkata Raman in 1928 and came to be known as Raman
The single slit setup is dependent on the slit width, distance, and wavelength of light source and the experiment aims to find out the relationship between these variables. When two slits are placed in the setup, an additional diffraction pattern will be observed within the single slit diffraction. These new fringes are equal in width unlike the first diffraction. The two setups have their own equations and the problem is to find out the difference of the two
Post-Processing Pipeline To Render God Rays This method can be used to render light beams caused by directly glancing at a partly occluded light source. In other words, this method fails if the source does not lie within the image borders. The fundamental principle of their approach is to bloom and blur parts of the scene around the position of the sun to simulate overexposure.  This post-processing is done in seven steps and three render targets- the final image, Temp0 and Temp1, which contain the same image with one-sixteenth the resolution of the original image. 4.1.
