Question
When a ray of light enters a glass slab, then
Options
A.its frequency and wavelehgth changes
B.its frequency does not change
C.only frequency changes
D.its frequency and velocity changes
Solution
When an electromagnatic wave entrs a medium (new), It undergoes changes in velosity
    v = nλ
This change in velosity bis due to change in wave-lengh. The frequency remains constant.
    v = nλ
This change in velosity bis due to change in wave-lengh. The frequency remains constant.
