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#
