A ray of light enters a spherical drop of water of refractive index `mu` as shown in figure.

Q. Select the correct statement:

A

Incident rays are partially reflected at point A.

B

Incident rays are totally reflected at point A

C

Incident rays are totally transmitted through A

D

None of these.

Text Solution

Verified by Experts

The correct Answer is:
A
A
From Snell’s law
`mu sinalpha=sinphi`
`sinalpha=1/mu sinphi`<`1/mu`
`alpha`is less than critical angle
