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

Planck's constant

B

charge of an electron

C

threshold frequency

D

work function of cathode metal

Text Solution

Verified by Experts

The correct Answer is:
a,c,d

The intercept of staright line for a graph between `E_(K)` and `v` on negligible energy axis gives the value of work function of cathode metal. The point where the straight line cuts the frequency axis, gives the value of threshold freqeuncy, where as the slope of st. line can help to find the planck's constant.
