The energy of one photon of this light is 4.85xx10^(-19)J.4.85×1019J.

Explanation:

I believe that you have to use the following equation to answer this question:

I should also note that Planck's constant has a value of 6.63 xx 10^(-34) J/s6.63×1034Js

We know the frequency and Planck's constant so all we have to do is plug the given values into the equation like so:

E = 6.63xx10^(-34)J/cancelsxx7.32xx10^(14)cancels^(-1)

E = 4.85xx10^(-19) J.
