An x-ray photon of energy 3.20 $\times$ 10^-15 J has what wavelength? A) 200 nm B) 62.1 pm C) 32.7 nm D) 5.73 pm E) 1.07 nm

Question

Quizplus · Accepted Answer

The energy of a photon can be related to its wavelength using the equation:
E = hc/λ
where E is the energy, h is Planck's constant, c is the speed of light, and λ is the wavelength.
Rearranging the equation, we get:
λ = hc/E
Plugging in the values given in the problem, we get:
λ = (6.626 x 10^-34 J s) x (3 x 10^8 m/s) / (3.20 x 10^-15 J) = 6.21 x 10^-11 m
Converting meters to picometers (pm), we get:
λ = 62.1 pm
Therefore, the answer is B.
