The energy of the waves is 6.5 * 10^-19 J.

What is the energy?

The energy of the wave could be obtained from the wavelength of the wave by by the use of the formula shown below;

E = hc/λ

h = Plank's constant

c = speed of light

λ = wavelength

Now we have;

h = 6.6 * 10^-34 Js

c = 3 * 10^8 m/s

λ =  305 * 10^-9

E =  6.6 * 10^-34 Js * 3 * 10^8 m/s/ 305 * 10^-9

E = 6.5 * 10^-19 J
