Question

In glass, the speed of red ray is _____
Violet ray.. Fill in the blanks

Answer 1

Answer:

HERE IS UR ANSWER

Explanation:

As, glass has refractive index(1.52) greater than air(1.00029), phase velocity of light reduces. Now, coming to your question, as violet light has shortest wavelength and red has the largest. So, Phase velocity of red is greater than of violet. Or, we can say, red travel faster than violet light.

Answer 2

Answer:

In glass ,The speed of red ray is lower than violet ray

Explanation:

It is because the red colour have longer wavelength
