What is the approximate energy of a photon having a frequency of 5 x 10^-24 hz? (h=6.6 x 10^-34 j-s) ?

To determine the frequency, we will use the equation: E = hv

Where

E is the energy of the packet

h is Planck’s constant

v is the frequency

since we know E and h, we have to rearrange the equation to solve for the frequency, so it would look like v = E/h

so plugging in our values:

v = E/h

= 5 x 10^-24 J / 6.626 x 10 ^-34 J/s

= 8 x 10^9 Hz
