Calculate the frequency associated with a photon of energy `3.3 xx 10^(-20)` J `(h=6.6 xx 10^(-34) Js)`.

Explanation

Energy = `E = 3.3 xx 10^(-20) J `
`h = 6.6 xx 10^(-34)` `E = hv`
`v = E/h = (3.3 xx 10^(-20))/(6.6 xx 10^(-34))`
`E = hv`
`v = E/h = (3.3 xx 10^(-20))/(6.6 xx 10^(-34))`
`= 0.5 xx 10^(14)`
`v = 5 xx 10^13 Hz`
