PLEASE HELP ME WITH THIS ONE QUESTION The color orange has a wavelength of 590 nm. What is the energy of an orange photon? (h = 6.626 x 10^-19, 1 eV = 1.6 x 10^-19 J)

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
