### wavelengths and energy of a photon

Is there any relationship between the size of a wavelength and the energy of a photon? Or is the energy of a photon only relative to the frequency of a wave because of the equation E=hv?

How does frequency relate to wavelength? Try writing an expression for frequency relating to wavelength and plug it into the equation you wrote.

When the size of the wavelength increases (more far apart) then frequency decreases and I believe this causes energy to decrease. If the wavelength decreases(less space in between), then frequency increases therefore energy increases, specifically electromagnetic radiation.
I found this on wikipedia:
"Photon energy is the energy carried by a single photon. The amount of energy is directly proportional to the photon's electromagnetic frequency and inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy."
