Answer:

Heyaa mate________________here is the answer to your question___^_^☟☟☺

____________________________________

☆ The photoelectric effect is the emission of electrons or other free carriers when light hits a material.

☆ The four properties of photons are :-

• Photons hv zero mass nd rest energy.

• Photons hv no electric charge.

• Photons are stable.

• Photons carry energy nd momentum which are dependent on frequency.

☆ a) On increasing the intensity of light__ :- Increasing the light intensity (photon energy per second per unit area) increases the rate at which electrons leave the metal, and the electrons have more kinetic energy.

b) Yes ..it will change as it increases photons per second that are emitted by the light source.
