## Michelson Interferometer

Michelson interferometer The Michelson interferometer was invented by the American physicist Michelson. Although it has a simple structure, it can measure very small distance differences, such as the size of an atomic nucleus. The Michelson interferometer consists of the following … more

## Double-Slit Experiment

Double Slit Experiment The double-slit experiment is the observation of the pattern that a single wavelength of light creates after passing through two slits. Light passes through each slit and then creates a light or dark pattern depending on interference. … more

## Phase array

Spinning radar In general, electromagnetic waves (radio waves) propagate in all directions. In this case, radio waves can be transmitted or received in any direction. However, as the distance increases, the strength of the radio wave decreases in proportion to … more

## Superposition and Interference

Superposition occurs when two or more waves pass through each other. When two or more waves superimpose, the amplitudes are added together. It creates constructive interference or destructive interference.

## Newton Ring

The Newton ring The interference of two reflections causes Newton rings. We can observe the Newton Rings when light is reflected from a plano-convex lens of a long focal length placed in contact with a plane glass plate. A thin … more

## Diffraction Grating

The diffraction grating is a transparent plate with very narrow lines on the surface. Light (photons) like to go in the same phase. In the same phase, constructive interference occurs. If the phases are different, the waves cancel each other … more

## Why does a CD reflect rainbow colors?

Adjust the wavelength of light to choose the color of light you want. If you adjust the angle of reflection correctly, the phases of the light may coincide. That angle is the angle at which light is reflected by interference. … more

## Thin Film Interference

Interference patterns seen in thin films If a thin oil film is floating on the water, you will see a beautiful pattern appear on the oil film. This is because the two waves interfere with each other. One wave is … more

## Chord, Just intonation, Equal temperament

This simulation is Works with Edge, FireFox, Chrome, Safari, Opera. does not works with Internet Explorer, Opera Mini. Due to the nature of the program, there may be some beats even in consonant sounds. Chord The sound of two or … more

## Young’s Double Slit

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

## Superposition

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
