Question

If each metal is hit with light at the minimum wavelength, can I vary the intensity of the light to start emitting electrons? Yes or no? Explain

Answer 1

Consequently the statement is FALSE

Step-by-step explanation:

The process of emission of electrons or photoelectric effect, was explained by Einstein, assuming that light behaves as formed by how many so-called photons and each one of them collides with an electron, therefore to start an electron the incident photon energy must be greater than the work function of the material.

E =K + Ф

By mentioning the intensity we increase the number of photons but we do not increase their energy.

Consequently the statement is FALSE
