Question

What is the energy of a photon whose frequency is 6.0x10^20 hz?

Answer 1

give me some answer choices and i will be happy to help

Answer 2

Energy of photon is given by formula

`E = h\\u`

here

h = Planck's constant

`h = 6.6* 10^(-34)`

`\\u = frequency = 6 * 10^(20)Hz`

now the energy is given by

`E = 6.6*10^(-34) * 6 * 10^(20)`

`E = 3.96 * 10^(-13) J`
