The energy of an x-ray photon of wavelength 3.0 × 10^-10 m is A) 1.0 × 10^-16 J. B) 9.9 × 10^-16 J. C) 6.6 × 10^-16 J. D) 2.2 × 10^-24 J. E) 3.2 × 10^-29 J.

Question

Quizplus · Accepted Answer

The energy of a photon is given by E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Substituting the given values, we get:
E = (6.626 × 10^-34 J s) × (3.0 × 10^8 m/s) / (3.0 × 10^-10 m)
E = 6.6 × 10^-16 J
Therefore, the correct answer is C, 6.6 × 10^-16 J.
