Question

Which of the following experiments or phenomena provided evidence for the particle nature of light?

Interference patterns observed during the double slit experiment.
Expulsion of electrons with varying frequencies of light observed in the photoelectron effect.
Polarization of light
The observed bending of light thought a prism and resulting spectrum.

Answer 1

Expulsion of electrons with varying frequencies of light observed in the photoelectron effect.

Step-by-step explanation:

Answer 2

Answer;

Expulsion of electrons with varying frequencies of light observed in the photoelectron effect.

Explanation;

• The photoelectric effect supports a particle theory of light in that it behaves like an elastic collision between two particles, the photon of light and the electron of the metal.
• Albert Einstein observed the photoelectric effect in which ultraviolet light forces a surface to release electrons when the light hits. He explained the reaction by defining light as a stream of photons, or energy packets.
