Answer:
Explanation:
Energy is directly proportional to frequency and it is given as:
E = hf
where h = Planck's constant
f = frequency
To get frequency, we use the formula of speed:
c = λf
where c = speed of light
λ = wavelength
=> f = c/λ
Therefore, the energy of the photon will be:
E = hc/λ
The energy of the photon is
