Physics Labs
Interactive physics, built for NEET. Rotate it, test yourself, remember it.
Dual Nature of Radiation and Matter
2 labsMatter Waves
Every particle is also a wave. Drag a slider to watch a cricket ball's wavelength shrink to nothing, then see why an electron in an atom has no choice but to form a standing wave. Includes a NEET formula decoder and the historic 1927 Davisson-Germer experiment.
Matter Waves 3D
Watch a 3D electron wave wrap around a nucleus. Rotate it with your finger. At integer wavelengths the wave closes cleanly — at fractions it fails. The same standing-wave principle that explains why orbits are quantized, in 3D.
Atoms & Modern Physics
2 labsHeisenberg 3D
Bohr's electron rides a fixed circular orbit. Heisenberg's jumps randomly inside a 90% probability sphere. Tap Trace path and watch the truth emerge — the 1s orbital is not a path. It is the record of where the electron has been.
Blackbody Radiation
Drag a temperature slider from human body heat to a blue supergiant. Watch Planck's curve shift, see why classical physics predicted an ultraviolet catastrophe, and understand Wien's law and Stefan-Boltzmann in real time.
