I found: $E = 5.08 \times 10^{- 19} J$ $E=5.08xx10^-19J$

In this case I would use Einstein's relationship:

$E = h \cdot ν$ $color(red)(E=h*nu)$

where the energy $E$ $E$ is equal to Planck's Constant, $h$ $h$ , times the freqency $ν$ $nu$ :

so:

$E = 6.63 \times 10^{- 34} \cdot 7.66 \times 10^{14} = 5.08 \times 10^{- 19} J$ $E=6.63xx10^-34*7.66xx10^14=5.08xx10^-19J$

What is the energy of a 7.66⋅10147.66 * 10^14 HzHz wave?
