### Why do shorter wavelengths have more energy than longer wavelengths?

I know short wavelengths (high frequency) have more energy than longer wavelengths, but I really don't know why. I partially understand why using the E=hc/lambda equation, but I do not understand the logic behind it.

I believe it is because shorter wavelengths have higher frequencies. I like to think about it in the perspective of how shorter wavelengths can travel faster or more of them can occur in a shorter time frame so it makes sense they would have more energy if they occur more consistently. When you compare these to long wavelengths which take longer to occur and generally occur less in the same time frame, we can see why they would have less energy.

The equation E = hv explains why shorter wavelengths have more energy than longer wavelengths. Shorter wavelengths equate to higher frequency due to the c = v*lambda equation, and frequency (v) is directly proportional to the energy of a photon

Shorter wavelength light means the electric and magnetic fields are changing more rapidly across the same time/space

This is because they have a higher frequency.
