Options

• slows down less and refracts more.

• slows down more and refracts less.

• slows down more and refracts more.

• slows down less and refracts less.

Answer 1

Inside the prism, during the dispersion of white light, compared to blue, red light slows down less and refracts less.

Explanation:

In a prism, red light has a lower frequency and longer wavelength than blue light, so it is slowed down less when it enters the prism and bends (refracts) at a smaller angle.
