Question

Determine which of the following photons has the highest and lowest energies:

A = 949 λ (nm)

B = 809 λ (nm)

C = 722 λ (nm)

Answer 1

Photon with the highest energy. =722 λ (nm)

Photon with the lowest energy. =949 λ (nm)

Reason :Photons with short wavelength have the most energy while those with long wavelength have the least energy.
