Question

light of two colours A and B pass through a glass prism .A deviates more than B from its path of incidence. Which colour has a higher speed in the prism

Answer 1

Answer: The correct answer is "B".

Explanation:

The color having shorter wavelength deviates more while the color having longer wavelength deviates less. The shorter wavelength bends more in comparison to the color having longer wavelength.

The speed of color having shorter wavelength is more than the speed of light having longer wavelength.

In the given problem that light of two colors A and B pass through a glass prism. A deviates more than B from its path of incidence.

Therefore, B's speed is more.  

Answer 2

Answer:

in this question b has a higher speed in the prism.

Explanation:

hope you get the answer!!!
