WebFor a light ray traveling through space (or vacuum), its propagation velocity is constant given by 3*10^8 m/s. Since velocity is constant, the frequency of the radiation changes upon any change in its wavelength. The relation between frequency, wavelength, and velocity of light is given by. c=λv. Where, v is the frequency of light. WebSolution. Verified by Toppr. When a ray of light passes from water to air, it travels from denser to rarer, so the speed of light increases. In a material medium, it travels at the speed of light until it hits an atom. It is then absorbed and re-emitted in the same direction, which takes a small amount of time. The more this happens, the slower ...
