### E=hv

In the E=hv equation what does the h represent?

h represents Planck's constant, which is 6.626*10^-34 J*s

I agree with the person above^. Also, if you ever forget, it's listed on top of the formula sheet we get during the test.

It's Planck's constant (6.626x10^-34 Jxs)!

It'll be given to us on the front sheet of a test with all the constants, I think

h is planck’s constant, which is 6.626*10^-34, and I like to remind myself that it is an extremely small number when I am making calculations.

### Re: E=hv

I understand how and when to use Planck's constant, but why do we use it? How was that specific number derived and what does it represent?
