Question

What equation relates energy to Planck's constant and photon frequency?

a) E=ν/h
b) E=λh
c) E=hλ
d) E=hν

Answer 1

The equation that relates energy to Planck's constant and photon frequency is E = hν.

Step-by-step explanation:

The equation that relates energy to Planck's constant and photon frequency is E = hν (option d). In this equation, E represents the energy of the photon, h is Planck's constant, and ν is the frequency of the photon.

This equation shows that the energy of a photon is directly proportional to its frequency. As the frequency increases, the energy of the photon also increases.
