Q. Blue light can cause photoelectric emission from a metal, but yellow light cannot. If red light is incident on the metal, then
Dual Nature of Radiation and Matter
A
photoelectric current will increase
19%
B
rate of emission of photoelectrons will decrease
22%
C
no photoelectric emission will occur
37%
D
energy of the photoelectrons will increase.
22%
Solution:
Threshold wave length is less than that of yellow light. So, the red light cannot cause photoelectric emission .
