Quantum & Nuclear Physics

Particles composing light with energy given by E=hf, where h is Planck's constant and f is the frequency of the wave.

Phenomenon where light ejects electrons from a material's surface if the light's frequency exceeds a threshold, with observations like energy of emitted electrons being proportional to light frequency.

Proposed by de Broglie, suggesting particles exhibit wave properties with a wavelength λ.

Process where a particle and its antiparticle annihilate to produce photons.

Bohr's model suggests the angular momentum of an electron in an orbit is quantized.

Mathematical function describing the quantum state of a particle, with the square of its amplitude representing the probability density of finding the particle in space.

Stated by Heisenberg, it limits the precision of pairs of physical properties like position and momentum.

Model demonstrating quantization of energy levels for an electron confined in a 'box', showcasing quantum mechanical properties.

Phenomenon where particles pass through a potential barrier despite lacking sufficient classical energy.

Experiment where alpha particles are scattered by a gold foil, leading to the discovery of the nucleus.

Nucleons within the nucleus have quantized energy levels, with transitions emitting or absorbing gamma rays.

Nearly massless and chargeless particle hypothesized to conserve energy, momentum, and angular momentum in beta decay.

Describes the rate of decay of a radioactive isotope using the activity A and decay constant λ.
