Question

What is the approximate frequency of a photon having an energy `5*10^-24` `J`?

Answer 1

The approximate frequency is `8xx10^(9) Hz`

Explanation:

To determine the frequency, we'll use the equation below:

• The energy of packet (`5xx10^(-24) J`) is known
• Planck's constant, h, has a value of `6.626xx10^(-34)J/s`

Since we know E and h, all we have to do is rearrange the equation to solve for the frequency, `v`:

`E/h=(cancelhxxv)/cancelh`

`E/h =v`

`(5xx10^(-24)cancelJ)/(6.626xx10^(-34)cancelJ/s)`

After you perform that calculation, you should end up with:

`8xx10^(9)s^-1` or `8xx10^(9) Hz`
