What is the relationship between the energy of a photon and the frequency of the electromagnetic radiation?.
- A.E = hf
- B.E = mc^2
- C.E = mv^2
- D.E = 1/2 mv^2
Model answer
What a good answer should say
- E = hf
Explanation
Why this works
The formula E = hf describes the energy of a photon (E) as directly proportional to its frequency (f), where h is Planck's constant. This relationship is fundamental in quantum physics and is essential for understanding the photoelectric effect.
