find the color of light that is known to have an energy of 4.59x10^-19joules

Question

Explanation too please.

Answer 1

E = h*frequency

Answer 2

I don't understand! ! :(

Answer 3

There's nothing to understand. Substitute for h (Planck's constant) and energy from the problem. Solve for frequency in Hz. Planck's constant should be listed in your text or notes. If not you can look on the web.
