**VERY SIMPLE!!! Please help!! - Energy of a gamma ray photon...**

## Homework Statement

The frequency of gamma radiation is 10[tex]^{22}[/tex] Hz. What is the energy of each gamma ray photon?

Planck's constant,

*h*, is equal to 6.6 x 10[tex]^{-34}[/tex] J*s.

## Homework Equations

Energy =

*h*

*f*

## The Attempt at a Solution

I'm having a problem with the units...

Energy = (6.6 x 10[tex]^{-34}[/tex] J*s)(10[tex]^{22}[/tex] Hz)

= (6.6 x 10[tex]^{-34}[/tex] J*s)(10[tex]^{22}[/tex] vib/s)

= (6.6 x 10[tex]^{-34}[/tex] J)(10[tex]^{22}[/tex] vib)

= 6.6 x 10[tex]^{-12}[/tex] J

What happens to the 'vibration' unit?

(note: I changed the Hz to vib/s. Is that correct?)
