Question

The maximum kinetic energy of electron emitted in the photoelectric effect linearly depends on the .................... of the incident radiations.

• A. temperature
• B. amplitude
• C. number
• D. frequency

Answer 1

The correct option is D frequency

The maximum kinetic energy of electron emitted in the photoelectric effect linearly depends on the frequency of the incident radiations.
The maximum kinetic energy of electron emitted in the photoelectric effect is equal to the difference in the energy of the incident radiation and the work function.
The energy of the incident radiation is proportional to its frequency.
