The wavelength of a photon that has an energy of 5.25 × 10^-¹⁹J is m. A) 3.79 × 10⁷ B) 2.38 × 10²³ C) 2.64 × 10⁶ D) 3.79 × 10^-⁷ E) 4.21 × 10^-²⁴

Question

Quizplus · Accepted Answer

The energy of a photon is given by E = hc/λ, where h is Planck's constant (6.626 × 10^-34 J·s) and c is the speed of light (3.00 × 10^8 m/s). Solving for λ gives λ = hc/E. Substituting the given energy into the equation gives λ ≈ 3.79 × 10^-7 m.
