Science Simulations
* This simulation take the spectral data from NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY. When heat is applied to the atoms, some electrons can have high energy levels and fall to the lower levels. Some electrons emit as much energy … more
What is light? A form of energy that brightly illuminates the world we live in is called light. Various electromagnetic waves, including visible light, are emitted from hot objects or objects with energy. Visible light is the part of the … more
How to calculate the area of a circle If you cut the circles and stick them together, they gradually become more rectangular. In this rectangle, the width is half of the circumference, and the height is the radius. Therefore, The … more
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 moves away, the wavelength … 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 crescent moon. And Venus … 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 and S2. Light passing … 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 an atom, electrons form … 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 the magnetic needle placed … 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 an interference pattern due … 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 radio wave. Electromagnetic radiation … 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 represent the actual wavelength … more
