    physical process in which the amount of absorbed light depends on concentration of the substance C, the thickness of the liquid layer d and a specific absorption coefficient α at a given wavelength λ. The phenomenon of light transmission through a sample can be described by the fraction of light at a specific wavelength λ that passes through the sample (Fig 3.7). If Io is the intensity of the incident light and I1 be the intensity of the transmitted light then the transmittance T can be expressed

  • Refraction Lab Report

    1923 Words  | 8 Pages

    Refraction: Refraction occurs when light enters a more or less optically dense medium, which therefore has a different refractive index (measure of the velocity light can travel at in the medium compared to in a vacuum in which it can travel at 2.9 x 108ms-1). This causes the light’s speed to increase or decrease, which results in the rays bending towards or away from the normal, so the position of the image formed is dependent on the refractive indices of the two media. For refraction to occur

    light energy for determining the concentration of substances in a solution. (Mark Garcia 2014). The instrument used is called spectrophotometer to distinguish different compounds since they absorb light at different wavelength. Some have wide range of wavelength and the shorter the wavelength the higher the energy. For one to know the absorbed light one has to put a cuvette into a sample holder with a solution and record the amount of light transmitted and absorbed through the solution. A concentration

    01. Introduction to sound Waves Sound is a progression of longitudinal or pressure waves that travel through air or different materials. Sound does not go in a vacuum. Like any waveform, sound has the qualities of wavelength, recurrence, plentifulness and pace or speed. Sound waves are made by the vibration of some item, similar to the cone in a radio amplifier. The waves are distinguished when they cause a locator to vibrate. Questions you may have include: 1. What is a depiction of sound

    the focal point, this is the cause of lens dispersion, where the colours in the light rays travel at different speeds when going through a lens, this causes there to be multiple focal points ; The blue focal point is shorter than the red, as its wavelength is shorter, you’ll get multiple image distances, this will create multiple images, one for each colour of the incidence beam. These different rays will then overlap to produce an image with blurry coloured edges. So sometimes when you’re viewing

    Theoretical Background Fluorescence Fluorescence is the ability of many natural and synthetic structures, known as fluorophores, to emit light when excited with light at specific wavelength. Fluorescence phenomena occur when an incident light photon interacts with an electron of a fluorophore. The incident light photon may transfer its energy to the electron of the fluorophore and hence the electron moves to a higher energy state. When the electron returns to its ground state, it loses energy
