Match the Column I with Column II when wavelength of light is 660 nm.
Column I | Column II | ||
(A) | Momentum of photon (in ) | (I) | |
(B) | Number of photons emitted per second by a 66 W source of monochromatic light | (II) | |
(C) | Number of photons emitted per second by a one watt bulb, if its efficiency is 20%. | (III) | |
(D) | The rate at which photons striking the surface, if the intensity of light is and surface area is (in per second) | (IV) |
Choose the correct answer from the options given below.
Text Solution
Verified by ExpertsA
Momentum of photon,
= 
= 
= 
Power of the source, 
No. of photons emitted,
Rate at which photons strike the surface,
Hence, A-(IV), B-(I), C-(II), D-III.
