Question

When an electron of an atom returns from an excited state to the ground state, it emits energy in the form of a photon. How does the change in energy level compare to the energy of the emitted photon?
A)It is less than the energy of the photon.
B)It is about one third the energy of the photon.
C)It is exactly half of the energy of the photon.
D)It is equal to the energy of the photon
E)It is exactly twice the energy of the photon.

Answer 1

What do you think??

Answer 2

A??

Answer 3

How so any explanations?

Answer 4

no, basically just a guess

Answer 5

Lets start off with what is a photon?

Answer 6

a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.

Answer 7

@Abhisar lol you are not hard to find :)

Answer 8

The energy transaction in such cases are always quantized, this means that the energy transaction will always be in the terms of photon.

Answer 9

@kingalex123 :)

Answer 10

so then, the answer would be?

Answer 11

That's you to tell me :)

Answer 12

Got it?

Answer 13
