As you can see, the wavelength of the red light shortens in the glass, and so does the speed of the light. But the frequency remains the same, and so does the color. Thus, red light of wavelength 700 nm in air will appear the same color as red light of wavelength 438 nm in this type of glass.
Each wavelength of light has a particular energy associated with it. Home Page. With R = 1. Other common colors of the spectrum, in order of decreasing wavelength, may be remembered by the mnemonic: ROY G BIV .
