wavelength frequency and energy problems answer key gy equation to find frequency: f = E / h. Use the wave equation: λ = v / f. Example: Find the wavelength of a photon with energy 3.3 × 10⁻¹⁹ J. Answer: f = E / h = (3.3 × 10⁻¹⁹ J) / (6.626 × 10⁻³⁴ Js) ≈ 4.98 × 10¹⁴ Hz λ = v / f May 6, 2026 Read more →
