The wave theory of light does not explain photoelectricity because

A.

light waves carry little energy

B.

particles cannot be emitted by waves

C.

the frequency of light waves too high

D.

there is a threshold wavelength for electron emission

E.

the wavelength of Light waves is too short

View answer & explanation

Correct answer is A

  • According to wave theory, after the light falls on a substance electrons are emitted after a small instant of time. However, in photoelectric effect, the electron emissions are immediate without a time delay.
  • ​The energy of a wave increases with increase in intensity. However, in photoelectirc effect, increase in intensity has no effect on the energy of electrons emitted. All that happens is the number of electrons emitted, increases.he energy of a wave grows as its intensity increases. In the photoelectronic effect, however, increasing the intensity has no influence on the energy of electrons released.
