Dual Nature of Radiation and Matter is an important chapter in CUET Physics that explains the wave–particle nature of light and matter. This topic introduces concepts such as the photoelectric effect, Einstein’s photoelectric equation, and the de Broglie hypothesis.
Students learn how light can behave both as a wave and as a stream of particles called photons, and how particles like electrons can also show wave-like properties.
Understanding these principles helps students grasp the foundation of modern physics. For CUET preparation, it is important to practice concept-based questions and numerical problems related to the photoelectric effect and de Broglie wavelength.
