Nuclear Physics and RadioactivityHard
Question
The figure shows the results of an experiment involving photoelectric effect. The graphs A, B C and D relate to a light beam having different wavelengths. Select the correct alternative
Options
A.Beam B has highest frequency
B.Beam C has longest wavelength
C.Beam A has highest rate photoelectric emission
D.Photo electrons emitted by B have highest momentum
Solution
Stopping potential frequency
Stopping potential frequency ∝
Saturation current ∝ rate of photo electron emission.Also, K.E. max = hv -
