Questions and Answers

According to the photoelectric effect, which of the following statements is true?

Light below a certain minimum threshold frequency can eject electrons.

Greater frequency of light results in greater energy of electrons. (correct)

Photons are massless particles that cannot transfer energy to electrons.

Light brightness is the only factor that determines the ejection of electrons.

What did Einstein propose in 1905 about light?

Light can only eject electrons when it is very bright.

Light is made up of particles called photons. (correct)

Light is unable to transfer energy to electrons during collisions.

Light is a wave that can eject electrons from metals.

What is the relationship between a photon's energy and its frequency?

The energy of a photon is not related to its frequency.

The energy of a photon is equal to its frequency.

The energy of a photon is directly proportional to its frequency. (correct)

The energy of a photon is inversely proportional to its frequency.
