Question

Which of the following option depicts the path of light correctly?

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

Given, refractive index of medium A $\left({\mu }_A\right)$ = 3 and refractive index of medium B $\left({\mu }_B\right)$ = 4.
Since, $\left({\mu }_A\right)$ = 3 < $\left({\mu }_B\right)$ = 4
So, medium A is a rarer medium then medium B.
Also, light is traveling from medium A to medium B
We know that when a ray of light is traveling from a rarer to a denser medium then it bends towards the normal.
