If a certain metal was irradiated by using two different light radiations of frequency 'x' and '2x' the maximum kinetic energy of the ejected electrons are 'y' and '3y' respectively the threshold frequency of the metal is

When a radiation of frequency 7.5xx10^(14)Hz strikes a metal surface, the maximum kinetic enegy attained by the emitted electrons is 1.6xx10^(-19)J . Calculate the threshold frequency of the metal.

The kinetic energy of electrons ejected by using light having frequency equal to threshold frequency (v_(0)) is:

The kinetic energy of electrons ejected by using light having frequency equal to threshold frequency (v_(0)) is

What will be the kinetic energy of emitted photoelectrons if light of threshold frequency falls on a metal?

The work function of a metal is 3.4 eV. A light of wavelength 3000Å is incident on it. The maximum kinetic energy of the ejected electron will be :

Light of frequency 4nu_0 is incident on the metal of the threshold frequency nu_0 . The maximum kinetic energy of the emitted photoelectric is

Light of frequency 4 v_(0) is incident on the metal of the threshold frequency v_(0) . The maximum kinetic energy of the emitted photoelectrons is

To emit a free electron from a metal surface a minimum amount of energy must be supplied.When light of frequency 7.21 * 10^14 Hz is incident on a metal surface, the maximum speed of the ejected electrons is 6 x 10^5 m/s . Calculate the threshold frequency for the metal.

A metal is irradiated with light of frequency 3.2xx10^(16)Hz . The ejected photoelectron has kinetic energy (3)/(4) the of energy of absorbed photon. The threshold frequency orf the metal would be :
