Wavelength and Energy are related in what way?

Explanation:
The key idea is that energy per photon is inversely related to wavelength. In quantum terms, a photon carries energy E = hν, where h is Planck’s constant and ν is the frequency. Since light’s speed is c = νλ, the frequency is ν = c/λ. Substituting gives E = h c / λ. This means shorter wavelengths correspond to higher energy per photon, and longer wavelengths correspond to lower energy per photon. For example, blue light (shorter wavelength) has more energetic photons than red light (longer wavelength). The inverse relationship here is fundamental for photons, even though the total energy of a beam also depends on how many photons are present.
