Answer:
D. shortest wavelength
Explanation:
Photons with the highest energy have the shortest wavelength. The shorter the wavelength, the higher the energy of a photon.
A photon is a quantity that transmits electromagnetic energy from one place to the other.
Energy, wavelength and frequency of a photon are connected using the expression:
E = h f = [tex]\frac{hc}{wavelength}[/tex]
E is the energy
h is the Planck's constant
f is the frequency.
