# Could you solve for frequency by dividing energy by Planck's constant?

Sep 5, 2017

Yes, according to $E = h f$ formula

#### Explanation:

$E = h f$ is a formula used to find the enegy of light or photon

$E =$ energy of light $\left(J\right)$
$h =$ Planck's constant$\left(6.63 \times {10}^{-} 34 J . s\right)$
$f =$ frequency of light $\left({H}_{z}\right)$

So to solve for $f$ using $E = h f$, we take $h$ to the left side and divide $E$ by $h$ then we get $f$ by itself.

Finally we get a new formula that looks like this,

$f = \frac{E}{h}$

I hope this helps.
