Question

How are the energy of infrared, visible light and ultraviolet rays related? And why?

Answer 1

The energy of these spectral bands are related through the Einstein-Planck formula:

E = h * f

with h the Planck's constant and f the frequency of the electromagnetic wave.

Since the (frequency of infrared) is < (frequency of visible) < (frequency of ultraviolet), from the Einstein-Planck relationship it follows that the (energy of infrared) < (energy of visible) < (energy of ultraviolet).

Answer 2

The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays

hope this helps change it up a little
