Thread: Energy directly proportional to frequency of wave ..?

How ? And Why???

Please Help
Thankyou

I assume you are referring to E=hf; the energy of a photon being proportional to its frequency.

How and Why? That's just the way the universe is, I guess.

Frequency is defined as the number of total oscillations per second, so if frequency is higher, then the number of complete oscillations that hit a point per second is more, hence more energy.

Or, slapping you in the face 10 times a second hurts more than 5 times a second.
