Infrared photons cause a particular piece of metal to emit photoelectrons.
Will photoelectrons be emitted when the metal is illuminated by visible light?

Answer:
According to Planck's relation, energy of a photon of a radiation corresponding to the frequency  is given by
E = h

Infrared rays have less frequency as compared to the frequency of the visible rays.
 Energy of infrared radiation is less than the energy of visible radiaion.

As per Einstein's photoelectric equation,

Incident photon ...
