What is the Relationship Between Wavelength of Light and the Quantity

Question

What is the relationship between wavelength of light and the quantity of energy per photon?
A) They have a direct, linear relationship.
B) They are inversely related.
C) They are logarithmically related.
D) They are separate phenomena.
E) They are only related in certain parts of the spectrum.

Accepted Answer

According to the Planck-Einstein relation, the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. This means that shorter wavelengths have higher energy photons, while longer wavelengths have lower energy photons. Therefore, wavelength and energy per photon are inversely related.
