A photon of wavelength 6630 
is incident on a totally reflecting surface. The momentum delivered by the photon is equal to
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
B
The momentum of the incident radiation is given as 
. When the light is totally reflected normal to the surface the direction of the ray is reversed. That means it reverses the direction of its momentum without changing its magnitude
