Right Answer is: A
SOLUTION
The energy of the photon using Einstein relation is given by:
\(E=hν \)
With c = ν λ
The energy equation can also be written as:
\(E=h\frac{c}{\lambda }\)
c = velocity of light
ν = frequency
λ = wavelength of the photon or color, taken into consideration
Observation:
- The energy of a photon varies directly with frequency, i.e. E ∝ ν
- The energy of a photon varies inversely with the wavelength, i.e. \(E\propto\frac{1}{\lambda}\)
