4.) The refractive indices of the different colors of light indicate that light of different colors travels at different speeds in the prism which accounts for the different degrees of bending. The greater the index of refraction (n) of a medium the slower the light travels in it. Study the table of (2) wavelength and (n) refractive indices for each color of light in a crown glass prism. Then, answer the questions below.
Answers & Comments
Answer:
The refractive index of materials varies with the wavelength (and frequency) of light. This is called dispersion and causes prisms and rainbows to divide white light into its constituent spectral colors. ... For visible light normal dispersion means that the refractive index is higher for blue light than for red.
