Explanation

Light comes in packets called photons. Photon energy E = hf = hc/λ where h is Plancks constant (6.63 × 10⁻³⁴ Js). Higher frequency = higher energy photons.

This explains the photoelectric effect: shining light on metal releases electrons. Below threshold frequency, no electrons escape regardless of intensity – photon energy matters, not just quantity.

UV light has high-energy photons (causes sunburn). Infrared has low-energy photons (felt as heat). This quantum nature of light revolutionized physics.
