Electrostatic potential is the amount of work done in bringing a unit positive charge from infinity to a point in an electric field. It is measured in volts (V). Capacitance is the ability of a system to store charge per unit potential difference, measured in farads (F). A capacitor consists of two conductors separated by an insulating medium, storing energy in the electric field between them. The capacitance depends on the surface area, separation distance, and dielectric material. The potentia...

The Bohr model of the hydrogen atom, proposed by Niels Bohr in 1913, describes electrons moving in fixed circular orbits around the nucleus. Each orbit corresponds to a specific energy level, and electrons can transition between levels by absorbing or emitting energy in discrete quanta. The model explains the hydrogen emission spectrum, where light is emitted as electrons drop to lower energy levels. Bohr’s theory introduced the concept of quantized energy states, successfully explaining atomi...

Energy levels in an atom refer to the fixed orbits where electrons reside around the nucleus. These levels, also called electron shells, are quantized, meaning electrons can only exist at specific energy states. The lowest energy level, or ground state, is closest to the nucleus, while higher levels are called excited states. Electrons absorb or emit energy in discrete packets (quanta) when transitioning between levels, often seen as light emission in spectra. The arrangement follows the quantum...

The dual nature of matter and radiation refers to the wave-particle duality, where particles like electrons exhibit both wave-like and particle-like behavior. Key concepts include photoelectric effect (Einstein’s equation: ) and de Broglie wavelength (). Numericals often involve calculating threshold frequency, stopping potential, work function, kinetic energy of emitted electrons, and de Broglie wavelength. Problems may also require applying Einstein’s photoelectric equation, finding electr...
