Science Hub
Beautiful, interactive visualizations of scientific concepts — built for Kerala University FYUGP students to explore physics, chemistry, and beyond.
Explore how current-voltage curves of a solar cell shift with time of day — visualizing Isc, Voc, and the maximum power point across morning, noon, and evening irradiance levels.
Launch Simulation →Watch electrons and holes come alive in real time. Drag the voltage slider to forward or reverse bias the junction — see the depletion region breathe, energy bands bend, and carriers surge or recede. The heart of every diode, LED, and solar cell, right in your browser.
Launch Simulation →Dip the wire loop, hold it in the flame — watch Ba glow pearl green, Sr burn crimson red, Ca turn brick red. All 8 metal ions from your inorganic lab, animated with real characteristic colours and emission wavelengths.
Launch Simulation →Select your acid, base, normality and indicator — watch the animated burette drip into the conical flask, observe the live pH curve, and calculate the unknown normality using N₁V₁ = N₂V₂ at the equivalence point.
Launch Simulation →Fire alpha particles at gold foil and watch history unfold in slow motion. Observe scattering, deflection, and back-reflection — then examine the ZnS screen, change variables, and discover the nuclear model of the atom step by step.
Launch Simulation →Drag the angle-of-incidence slider and watch white light split into the full ROYGBIV spectrum in real time. Every ray is computed live with Snell's Law using real wavelength-dependent refractive indices — with normals, angle labels, and deviation readout.
Launch Simulation →Adjust slit separation, wavelength, and screen distance in real time. Watch coherent Huygens wavefronts expand from two slits, interfere constructively and destructively, and paint the classic bright-dark fringe pattern — with a live intensity graph.
Launch Simulation →Sweep voltage from reverse breakdown to forward conduction — watch the I-V curve plot live. Observe the sharp Zener breakdown knee, leakage region, and explore voltage regulation. Real semiconductor physics, fully interactive.
Launch Simulation →Vary voltage and resistance, watch current change in real time, and plot a live V–I graph to verify V = IR. Features a live circuit with ammeter, voltmeter, observation table, two-resistor comparison, and straight-line graph fit.
Launch Simulation →Discover why LEDs emit different colours, how bandgap energy determines wavelength, and how current controls brightness. Simulate 8 LED types — from IR to UV — with live I-V curve, emission spectrum, and glowing LED visualisation.
