Question

Choose the answer that explains the photoelectric effect.

Answer 1

the first one is D idk what the second one is

Answer 2

1.

Answer:

Metallic plates emit electrons only when light of a certain minimum frequency shines on them.

Explanation:

As we know by Einstein's equation of energy

$E = \phi + KE$

here we know that

$\phi$ = work function of metal

KE = kinetic energy of ejected electrons

E = energy of incident light

So here electrons will eject only when light of sufficient minimum energy will incident on the metal plate.

2.

Answer:

showed that individual photons have wave characteristics

Explanation:

Taylor did experiment with the source of light with very small intensity of light and then got the result of interference of light.

So here his experiment concluded that all light will show interference only due to one photon also.

So his experiment shows that one photon will give wave characteristics
