If we go on increasing the wavelength of light incident on a metal surface, what change in the number of electrons and the energy take place?

A xenon are lamp is covered with an interference filter that only transmits light of 400 nm wavelength. When the transmitted light strikes a metal surface, a stream of electrons emerges from the metal. If the intensity of the light striking the surface is doubled, then

Assertion : When certain wavelength of light fall on metal surface it ejects electron. Reason : Light was wave nature.

When an X -ray photon collides with an electrons and bounces off, its new frequency

In a photoelectric effect experiment , photons of energy 5 eV are incident on metal surface . They liberate electrons which are just stopped by an electrode at a potential of 3.5 V with respect to metal . The work function of the metal surface in eV is :

Statement 1: Though light of a single frequency (monochromatic light) is incident on a metal, the kinetic energies of emitted photoelectrons are not equal. Statement 2: The energy of electrons just after they absorb photons incident on metal surface may be lost in collision with other atoms in the metal before the electron is ejected out of the metal.

When yellow light is incident on a surface , no electrons are emitted while green light can emit. If red light is incident on the surface , then

Monochromatic light incident on a metal surface emits electrons with kinetic energies ranging from 0 to 2.5 eV. What is the least energy of the incident photon, if for removing the tightly bound electron from the metal surface an energy of 4.3 eV is required ?

When the photons of energy hv fall on a photosensitive metallic surface of work function hv_(0) , electrons are emitted are from jthe surface. The most energetic electron coming out of the surfece have kinetic energy equal to
