Answer:
Explanation:
Given:
- wavelength of light in the air,
- time taken to travel from the source to the photocell via air,
- time taken to reach the photocell via air and glass slab,
- thickness of the glass slab,
<u>Now we have the relation for time:</u>
hence,
c= speed of light in air
For the case when glass slab is inserted between the path of light:
(since light travel with the speed c only in the air)
here:
v = speed of light in the glass
Using Snell's law:
A, electromagnetic radiation
