Complete the following statement about photo electric effect. The radiations having minimum frequency called............... falls on a metallic surcace, electrons are emitted from it. The metal which emits photoelec trons are called........... The kinetic energy of pho toelectrons emitted by a metal depends on of.......... the radiations.

The stopping potential of the electrons emitted in a photoelectric experiment is V. The de-Broglie wavelength of the electron when it is emitted from the metal surface will be
