Answer:
The correct answer is - 2.10 eV.
Explanation:
To calculate the energy of a photon of a specific wavelength light, the following formula can be used:
E = h * c / λ = h * f ,
where,
E = energy of a photon.
h = Planck constant,
c = speed of light,
λ = wavelength of a photon,
f = frequency of a photon.
Putting the given value of orange photon:
E = h * c / λ
= (6.626 x 10^-19)*(3*10^8)/590
= 3.36685738E-19 or 2.1014 eV
