What is the equation used to calculate the energy transferred during the photoelectric effect?.
- A.E = hf
- B.E = mc^2
- C.E = QV
- D.E = 1/2 mv^2
Model answer
What a good answer should say
- E = hf
Explanation
Why this works
The equation E = hf relates the energy of a photon to its frequency, which is fundamental in the photoelectric effect. Here, E is the energy, h is Planck's constant, and f is the frequency of the light.
