The wavelength of a photon that has an energy of 6.33 × 10^-18 J is ________ m. A)3.79 × 10^-7 B)3.10 × 10^-8 C)2.38 × 10²³ D)4.21 × 10^-24 E)9.55 × 10¹⁵

Question

Quizplus · Accepted Answer

We can use the equation E = hc/λ, where E is the energy of the photon, h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Rearranging this equation, we get λ = hc/E. Plugging in the given values, we get λ = (6.626 × 10^-34 J s) × (2.998 × 10^8 m/s) / (6.33 × 10^-18 J) = 3.10 × 10^-8 m, which corresponds to choice B.
