Question

Quizplus · Accepted Answer

The energy of a photon is calculated using the formula E = hc/λ, where h is Planck's constant (6.626 × 10^-34 J·s), c is the speed of light (3.00 × 10^8 m/s), and λ is the wavelength in meters (525 nm = 525 × 10^-9 m). Substituting these values gives E ≈ 3.79 × 10^-19 J.
