Question

Quizplus · Accepted Answer

The energy of a photon (E) can be calculated using the formula E = hc/λ, where h is the Planck's constant, c is the speed of light, and λ is the wavelength. Rearranging the formula, we get λ = hc/E. Substituting the given values, λ = (6.626 x 10^-34 Js) x (2.998 x 10^8 m/s) / (8.63 x 10^-12 J) = 2.30 x 10^-7 m = 2.30 x 10^-14 m (in scientific notation with the correct number of significant figures). Therefore, the answer is B.
