Physics
Particle Nature of Light: The Photon
प्रकाश की कण प्रकृति: फोटॉन
This Class 12 Physics topic from Chapter 11, “Dual Nature of Radiation and Matter,” introduces the photon as the quantum or discrete packet of light energy. Students learn how photon energy is related to frequency through E = hf and how its momentum is expressed as p = h/λ. The topic connects these ideas with the photoelectric effect, helping students understand why light can behave like particles and how intensity, frequency, and wavelength influence photon energy and related observations.
