If the work function of a metal is `'phi'` and the frequency of the incident light is `'v'`, there is no emission of photoelectron if

The work function of a metal is 4 eV. What should be the wavelength of the incident radiation for the emission of photoelectrons of zero velocity ?

The photoelectric work function for a metal surface is 2.4eV.If a light of wavelength 5000Ais incident on the surface of the metal, find the threshold frequency and incident frequency. Will there be emission of photoelectrons or not?

The work function for a metal surface is 2.2 eV. If light of wavelength 5000 overset (@)(A) isincident on the surface of the metal,find the threshold frequency and incident frequency.Will there be an emission of photoelectrons or not?

What is the work function of a metal if light of minimum frequency 8xx10^(13) Hz is required for emission of photo electrons?

When the frequency of light incident on a metallic plate is doubled the KE of the emitted photoelectron will be

Work function of metal is phi wavelength of incident light is lambda .Which condition should be followed for not emitting the photo-electron?

Work function of a photosensitive metal is 1.875 eV. Calculate the wavelength of incident light, which will just cause the emission of photoelectrons.

The threshold frequency for certain metal is v_0 . When light of frequency 2v_0 is incident on it, the maximum velocity of photoelectrons is 4xx10^(6) ms^(-1) . If the frequency of incident radiation is increaed to 5v_0 , then the maximum velocity of photoelectrons will be
