If the frequency of light in a photoelectric experiment is doubled, the stopping potential will

A

be doubled

B

be halved

C

become more than double

D

become less than double

Text Solution

Verified by Experts

The correct Answer is:
C
Einstein's formula
`K_(max1)=eV_(1)+phi`
if freqeuncy is doubled,
`K_(max2)=eV_(2)+phi gt 2K_(max1)`

If the frequency of light in a photoelectric experiment is double then maximum kinetic energy of photoelectron

A light beam containing a number of wavelengths is used in an photoelectric experiment. The stopping potential :

Assertion: If frequency of incident light is doubled, the stopping potential will also become two times Reason: Stopping potential is given by V_0 = (h)/(e ) (v-v_0)

If the frequency of incident light is tripled, the stopping potential will

In a photoelectric experiment, it was found that the stopping potential decreases from 1.85 V to 0.82 V as the wavelength of the incident light is varied from 300nm to 400nm. Calculate the value of the Planck constant from these data.

Light of frequency 1.5 times the threshold frequency is incident on a photosensitive material, photo electric current is emitted. If the frequency of light is halved and intensity is doubled, the photoelectric current becomes

In a photoelectric experiment anode potential is ploted against plate current.

In an experiment on photoelectric effect the frequency f of the incident light is plotted against the stopping potential V_(0) . The work function of the photoelectric surface is given by ( e is the electronic charge)

The threshold frequency for a certain photosensitive metal is v_0 . When it is illuminated by light of frequency v=2 v_0 , the stopping potential for photoelectric current is V_0 . What will be the stopping potential when the same metal is illuminated by light of frequency v=3v_0 ?

K_("max") (in eV) = 3, and frequency of light (in Hz) =1xx10^(15) for a metal used as a cathode in a photoelectric experiment. The threshold frequency of light for the photoelectric emission from the metal is -
