Sound waves, all types of electromagnetic waves, and water waves can be dispersed according to wavelength. Dispersion occurs whenever the speed of propagation depends on wavelength, thus separating and spreading out various wavelengths.
Newton's prism experiment. Let's explore how Sir Issac Newton experimentally proved that white light is made of all the colours of the rainbow. Created by Mahesh Shenoy.

Consider the example of the ruler talked about in the video. The image of the tube light formed from the upper section of the ruler is seen to have red and blue colourations. However, white light is also seen in the middle. The answer to this lies in the magnitude of the angle of prism.

Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue and violet. The separation of visible light into its different colors is known as dispersion .
Aug 16, 2021 · The spreading of white light into its full spectrum of wavelengths is called dispersion. Rainbows are produced by a combination of refraction and reflection and involve the dispersion of sunlight ….
Jun 3, 2020 · A prism is a transparent 3-dimensional object made of glass and surrounded by intersecting planes, some of which are identical to one another. The most critical parameters of a prism are the angle and material that determines its purpose.

Jul 2, 2024 · Prism, in optics, a piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light. An ordinary triangular prism can separate white light into its constituent colours, called a spectrum. Each colour, or wavelength, making up the white.
