Question

Quizplus · Accepted Answer

The energy of a photon can be calculated using the formula:

E = hc/λ

where h is Planck's constant, c is the speed of light, and λ is the wavelength of the radiation.

Substituting the given values, we get:

E = (6.626 × 10^-34 J·s)(2.9979 × 10^8 m/s) / (0.122 m)
E = 1.63 × 10^-24 J

Therefore, the correct answer is C.
