Question

describe the photoelectric effect and explain why it made modifications to the Rutherford model necessary

Answer 1

Answer:

According to the Rutherford model, light of any energy should be able to make electrons leave the atom and be emitted.

The energy of the emitted electrons should be related to the intensity of the light.

Electrons are emitted only for certain wavelengths, and those wavelengths vary from atom to atom. The energy of the emitted electrons depends on the energy of the light, not its intensity.

Answer 2

Answer:

photoelectric effect and the modifications to the Rutherford model  is necessary

Explanation:

Photoelectric effect refers to emission of electrons when a light of certain frequency falls into a metal surface or a metal atom.

Rutherford, through his alpha particle scattering experiment, proposed the emission of electrons, in which he used a thin gold foil and high energy alpha particle were directed to the foil. He suggested that any light can emit electron from any metal surface.
