Answer:The energy of the photon is this light is $2.66\times 10^{-19} Joules$ .

Explanation:

Wavelength of the electromagnetic radiation = 745 nm = $7.45\times 10^{-7} m$

$1m =1\times 10^{-9}nm$

Energy of the photon will be given by Plank's equation:

$E=\frac{hc}{\lambda }$

$E=\frac{6.626\times 10^{-34} J s\times 3\times 10^8 m/s}{7.45\times 10^{-7} m}$

$E=2.66\times 10^{-19} Joules$

The energy of the photon is this light is $2.66\times 10^{-19} Joules$ .
