WebFeb 20, 2024 · 33. Ole Rømer did not measure a change in the frequency of light. He measured an apparent change in the orbital period of Io, one of Jupiter's moons. The orbit of Io can be measured very accurately by observing when it enters or leaves the shadow of Jupiter. When the Earth is moving away from Jupiter, Rømer noted that the orbit of Io … WebApr 1, 2024 · So according to equation (1) velocity of light is directly proportional to the wavelength. So violet color has minimum velocity of light and red color has maximum velocity of light when it passes through the glass. Hence the red color of white light travels fastest in the glass. Hence option (A) is the correct answer.
