How does the energy associated with waves change as a wavelength changes?

The energy associated with photons in an electromagnetic waves increases as the wavelength decreases. The equation is E = hc/λ, where E is energy of a photon, h is Planck's constant (6.62606957×10-34 J.s), c is the speed of light in a vacuum (299,792,458 m/s) and λ is wavelength.
