Snow and ice, airborne particles, and certain gases have high albedos and reflect different amounts of sunlight back into space.

WebThe refractive index (µ) of water is 1.33 and in air, the speed of light(c) is measured to be 3 x 108 ms-1. With the given values calculate the speed of light in the water. ... It can also be described as the ratio of the velocity of a light ray in an empty space to the velocity of light in a substance, n = c/v. Ques. What is meant by ... WebThe refractive index for red light in glass is slightly different than for violet light. Violet light slows down even more than red light, so it is refracted at a slightly greater angle. The refractive index of red light in glass is 1.513. … dr wolff catherine
Optical properties of water and ice - Wikipedia
WebA refractive index is a property of the material itself. Now an effective refractive index can be given for an optical component (e.g. a waveguide) as a measure of the overall delay of a light beam in that component. This is not a property of the material the optical fibre is made of, but an effective property of the optical fibre altogether ... WebThe refractive index is the measure of bending of a light ray when passing from one medium to another. It can also be defined as the ratio of the velocity of a light ray in an empty … WebMay 8, 2024 · If you have an index of refraction that is homogeneous and isotropic It is when averaged over the universe, but it isn't if you look at individual gravitating systems, like a galaxy or a star system or an individual gravitating mass like a star or a planet (or a black hole).
