NettetCorrect option is C) The blue colour of the sky is due to the scattering of light by small particles of the atmosphere (air molecules). When white light (from the sun) enters the earth's atmosphere, it gets scattered away due to the atmospheric particles. Since blue colour has the minimum wavelength, so blue colour scatters the most and thus ... Nettet15. des. 2024 · (b) Red light is least scattered in the atmosphere. (c) Scattering of light Lakes place as various colours of white light travel with different speed in fir. (d) The fine particles in the atmospheric air scatter the blue, light more strongly than red. So the …

21. which of the following statements is not true for scattering of light?
NettetAt noon, the sun is at the nearest point to earth. Hence light has to travel very small distance therefore results in less scattering. During sunrise and sunset, the sun is at the farthest position. Here blue light gets scattered off and the red light, due to its larger wavelength, can travel a longer distance and hence reach our eyes. Nettet38 minutter siden · Scattered rain and snow could still fall through around 8 PM or 9 PM, then most of any remaining snow should stay over the Grand Mesa and the High Country through Friday night and early Saturday ... The fraction of light scattered by scattering particles over the unit travel length (e.g., meter) is the number of particles per unit volume N times the cross-section. For example, the major constituent of the atmosphere, nitrogen, has a Rayleigh cross section of 5.1 × 10 −31 m 2 at a wavelength of 532 nm (green … Se mer Rayleigh scattering , named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the Se mer The size of a scattering particle is often parameterized by the ratio where r is the particle's radius, λ is the wavelength of the light and x is a dimensionless parameter Se mer When the dielectric constant $${\displaystyle \epsilon }$$ of a certain region of volume $${\displaystyle V}$$ is different from the average dielectric constant of the medium $${\displaystyle {\bar {\epsilon }}}$$, then any incident light will be scattered … Se mer Rayleigh scattering is also an important mechanism of wave scattering in amorphous solids such as glass, and is responsible for … Se mer In 1869, while attempting to determine whether any contaminants remained in the purified air he used for infrared experiments, John Tyndall discovered that bright light scattering off nanoscopic particulates was faintly blue-tinted. He conjectured that a … Se mer The expression above can also be written in terms of individual molecules by expressing the dependence on refractive index in terms of the molecular polarizability α, … Se mer The strong wavelength dependence of the scattering (~λ ) means that shorter (blue) wavelengths are scattered more strongly than longer (red) wavelengths. This results in the indirect blue … Se mer ryan clark peopleshare
