Question

A certain shade of blue has a frequency of `7.32 * 10^14` `Hz`. What is the energy of exactly one photon of this light?

Answer 1

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

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/s`

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.`
