我们知道,色光的频率是由光源决定的, 与传播的媒质无关．由于色光的颜色、光子的能量(hv)都由频率决定,因此,色光在不同媒质中传播时,其频率、颜色和光子的能量都保持不变．在媒质中光速v=c/n,光波的波长λ= We know that the frequency of shades is determined by the light source, independent of the medium in which it is transmitted. Due to the color of the light, the energy (hv) of the photon is determined by its frequency, so the color, light and the energy of the photon remain unchanged when they propagate in different media. The speed of light in the medium v ​​= c / n, the wavelength of light wave λ =
