Question

Quizplus · Accepted Answer

The energy of a photon is calculated using the formula E = hc/λ. Substituting the given values (h = 6.626 × 10^-34 J·s, c = 3 × 10^8 m/s, λ = 500 nm = 500 × 10^-9 m), we find E ≈ 3.97 × 10^-19 J. Converting to electron volts (1 eV = 1.602 × 10^-19 J), E ≈ 2.48 eV.
