Question

2.a) Which is refracted most by a prism, red light
or blue light?
b) Explain your answer.​

Answer 1

Explanation:

Violet light is refracted the most by a prism. When white light passes through a glass prism, violet colour has the minimum speed and a short wavelength. As violet has a short wavelength, it undergoes the maximum deviation and hence appears at the bottom of the spectrum.
