Modern & Quantum Physics
Journey into the strange and fascinating world of the very small. Explore the particle-wave duality, quantized energy levels, and the powerful forces locked within the atomic nucleus.
Photoelectric Effect
Shine light on a metal surface to eject electrons, demonstrating the particle nature of light (photons).
Rutherford's Model
Recreate the gold foil experiment to discover the dense, positively charged nucleus of the atom.
Bohr's Model
Visualize quantized electron orbits and energy level transitions that produce atomic spectra.
Hydrogen Spectrum
See the specific spectral lines emitted by a hydrogen atom as its electron jumps between energy levels.
Nuclear Fission
Trigger a chain reaction by splitting heavy nuclei, releasing tremendous amounts of energy.
Nuclear Fusion
Combine light nuclei to form heavier ones, the process that powers stars and releases even more energy.
Semiconductors
Explore the band structure of solids and understand how doping creates n-type and p-type semiconductors.
