Dispersion of white light by a glass prism occurs because
A
white light consist of a mixture of seven different colour
B
the refractive index of glass is different from each constituent colour of white light
C
the speed of each colour of light in the glass is proportional to the refractive index of glass for each colour
D
the speed of each colour of light in the glass is proportional to the angle of refraction in he prism
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Dispersion of white light by a glass prism occurs because the refractive index of glass varies for each color. This difference causes each color to bend at a different angle, resulting in a spectrum of colors.
