Science Simulations
Doppler Effect By listening to the ambulance’s siren, we can tell if the ambulance is coming or going. When an ambulance approaches with a siren, the sound wave’s wavelength becomes shorter (higher note), and when it … more
Venus’ changes in phase and size are strong evidence of ‘Heliocentrism.’ Venus looks like a crescent moon or a full moon, depending on its angle to the sun. Venus is large when it looks like a … more
You can adjust the spacing and position of the slits. Young’s double slit experiment Young’s interference experiment is as follows: The light diffracted from the small holes S0 on-screen ‘A’ passes through the small holes S1 … more
Orbital An atom has an atomic nucleus with a (+) charge at the center and electrons with a negative charge around it. Electrons are arranged according to certain rules (wave functions), which are called ‘orbitals.’ In … more
Magnetic field around magnet The space where the magnetic force of the magnet acts is called a ‘magnetic field.’ The direction of the magnetic field is determined in the direction indicated by the N pole of … more
Superposition and interference of waves Two matters cannot be in the same location. But, two or more waves can be in the same space and at the same time. Throwing two stones into the pond creates … more
Whenever electric charge (such as an electron) accelerates, it gives out energy in the form of electromagnetic radiation. For example, electrons moving up and down a radio antenna produce a type of radiation known as a … more
This simulation assumed that a candle emits all its energy in only one specific wavelength. The power of the candle is assumed to be 50W. The emitted wave diagram is for understanding only and does not … more
A diode is an electronic component that conducts current primarily in one direction. It has low resistance in one direction, and high resistance in the other. A diode is made by joining an n-type and p-type … more
A thermometer is a device used to measure temperature. There are several types of thermometers, depending on how the temperature is measured. Thermal Expansion: Uses the principle that the volume expands with increasing temperature. Mercury thermometer, … more
All naturally occurring elements CAN exist as a solid, liquid, or gas, and all will have at least one triple point. (except Helium) The triple point is the unique combination of temperature and pressure at which … more
