### Proportional sign

What is the proportional sign that can be used between E (energy) and v (frequency) in the E=hv equation?

I'm not sure if this is what you mean, but the symbol ∝ is used for variables that are directly proportional to each other!

Energy is also directly proportional to frequency in that equation so as the frequency increases, the energy increases as well.

∝ is the sign! Basically instead of writing E = hv, you could write E ∝ v, which means that E is proportional to v (by a factor of h).

I agree with this. This shows that E and v are proportionate to each other.
