The energy of a photon is inversely proportional to its

photon energy, E= hv; v⟶frequency

E= h $\frac{c}{\lambda }$

Eα$\frac{1}{\lambda }$

So basically in above formula as we can see photon energy is directly proportional to its frequency and inversely proportional to wavelength.

photons are basically the energy packets which occur due to electron being transit from higher to lower level.
