The energy of a photon is ________ proportional to its wavelength. The energy of a photon is ________ proportional to its freque

topjm [15]

Answer: Inversely , Directly

Explanation:

The energy of a photon is inversely proportional to its wavelength and directly proportional to its frequency.

As can be seen from this equation;

E = hv = h c / ∧

Where E = Energy of a photon

v = Frequency

h = Planck Constant

c = speed of light

∧ = Wave length
