Ejection of electrons from the metal surface when a beam of suitable frequency light radiation falling on it is called as

The maximum velocity of electrons emitted from a metal surface is v when the frequecny of light falling on it is f. The maximum velocity when the frequency becomes 4f is

Assertion : The number of electrons ejected from a metal surface depend upon the frequency of light. Reason : There is a time lag between the striking of light beam and the ejection of electrons from the metal surface.

Energy required to stop the ejection of electrons from certain metal plate was found to be 0.2 eV when an electromagnetic radiation of 330 nm was made to fall on it the work function of the metal is

Assertion : Kinetic energy of photo electrons emitted by a photosensitive surface depends upon the intensity of incident photon. Reason : The ejection of electrons from metallic surface is possible with frequency of incident photon below the threshold frequency.

Assertion (A) : Kinetic energy of photoelectrons emitted by a photosensitive surface depends upon the frequency of incident photon. Reason (R ): The ejection of electrons from metallic surface is possible with frequency of incident photon below the threshold frequency.

The maximum velocity of the photoelectrons emitted from the surface is v when light of frequency n falls on a metal surface. If the incident frequency is increased to 3n, the maximum velocity of the ejected photoelectrons will be

The maximum velocity of the photoelectrons emitted from the surface is v when light of frequency n falls on a metal surface. If the incident frequency is increased to 3n, the maximum velocity of the ejected photoelectrons will be:

A beam of light of certain intensity and wavelength ejects photoelectrons from a metal surface. This beam is then replaced by another beam of less intensity and smaller wavelength . As a result
