Physics Question on Dual nature of matter
A photocell employs photoelectric effect to convert :-
A
change in the frequency of light into a change in the electric current
B
change in the frequency of light into a change in electric voltage
C
change in the intensity of illumination into a change in photoelectric current
D
change in the intensity of illumination into a change in the work function of the photocathode.
Answer
change in the intensity of illumination into a change in photoelectric current
Explanation
Solution
The photoelectric current is directly proportional to the intensity of illumination. Therefore a change in the intensity of the incident radiation will change the photocurrent also.
