Detailed Solution

According to Max Planck’s equation,

E=hcλeqn1

Here h is Planck’s constant and c is speed of light. 

The wave length of photon λ = 450nm

h=6.625×10-27ergs.sec

c=3×1010cm/sec

From equation 1, the energy of photon is

E=6.625×10-27ergs.sec×3×1010cm.sec-1450×10-7cmE=4.36×10-12ergs
