<u>Answer:</u> The value of energy change is
<u>Explanation:</u>
To calculate the energy of one photon, we use Planck's equation, which is:
where,
h = Planck's constant =
c = speed of light =
= wavelength = 500 nm = (Conversion factor: )
Putting values in above equation, we get:
Hence, the value of energy change is
