The maximum kinetic energy of the emitted photoelectrons against frequency `upsilon` of incident radiation is plotted as shown in Fig. This graph help us in determining the following physical quantities

A

work function of the cathode-metal

B

threshold frequency

C

Planck's constant

D

charge on an electron

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Intercept of straight line on negative energy axis gives the value of work function of the cathode metal. The point where the straight line cuts the frequency axis gives the value of threshold frequency while the slope of straight line provides the value of Planck's constant.
