Find the energy of a photon that
a corresponds in light frequency at `3 xx 10^(6) Hz`
b. Has a wavelength of `300 nm`

Explanation

Energy of photon
`E = hv`
`= 6.626 xx 10^(-34) Js xx 3 xx 10^(6)s^(-1)`
`= 1.98 xx 10^(-27)J`
b. Energy of photon
`E = hv = (hc)/(lambda)`
`= (6.626 xx 10^(-34) J s xx 3 xx 10^(8) m s^(-1))/(300 xx 10^(-8) m)`
`= 6.626 xx 10^(-19) J`
