Question

How much energy does an EM wave have if it has a frequency of 4.8 x 10 14 Hz

Answer 1

I don't know how much energy the entire wave has. Each photon has energy

`E=h \\u=6.6 * 10^(-34) \textrm{ J s} * 4.8 * 10^(14) \textrm{ Hz} = 3.2 * 10^(-19) \textrm{ Joules}`

Answer: 3.2×10⁻¹⁹ Joules
