Rainbows are formed when the rays of sunlight pass through the tiny water droplets or vapours present in the environment during or after rain. The water droplets here, tend to work as a prism and are used to split the ray of light into seven distinct colours with the help of the dispersion phenomenon.
Compact disks are readable and writeable data storage devices. If you hold a compact disk in hand with its mirror face facing towards the light source, you can easily observe a multicoloured pattern that gets formed on its surface. The existence or the formation of this coloured pattern on the surface of the disk is a prominent example of the dispe...
Petroleum and water are immiscible liquids. Petroleum has a low density as compared to water, which is why it tends to rest over the water surface. When a ray of light from the sun or any other source of light falls on the surface of the oil that is spilt on the water surface, a pattern of coloured light due to the dispersion phenomenon gets formed...
The dispersion phenomenon exhibited by the soap bubbles can be verified easily by observing the colourful spectrum of light that gets formed over its surface when light falls on its surface.
A prism is a piece of laboratory equipment made up of glass or silicon that is generally used to display the existence of dispersion phenomenon in real life. When a ray of white light is made to strike the surface of a prism, it gets split into a spectrum of light. The output light obtained as a result is slightly bent in nature. The bending of lig...
Plastic rulers are one of the most common examples of objects present in our real life that are capable of exhibiting the dispersion phenomenon. A plastic ruler is generally translucent in nature. When such a ruler is held at a particular angle and is exposed to white light, it tends to produce a spectrum of light as a result. The dispersion phenom...

Measures of dispersion, such as variance, are positive real numbers that describe the extent of variability in data. Understand measures of dispersion using solved examples.
This is called dispersion. Key points. The spectrum of white light is produced because different colours of light travel at different speeds in glass. Red light is slowed down least by glass and...
dispersion, in wave motion, any phenomenon associated with the propagation of individual waves at velocities that depend on their wavelengths. Waves of any type can be described by a dispersion relation in which the wave frequency ω is given in terms of the wavenumber k, where k = 2π/λ, where λ is the wavelength.

Mar 21, 2023 · There are two main types of dispersion: chromatic dispersion and modal dispersion. Chromatic dispersion occurs when light splits into its various colors, as seen in a rainbow. This happens because different colors of light have different wavelengths and travel at different speeds through a medium.
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 into a continuous distribution of colors. Dispersion produces beautiful rainbows but also causes problems in certain optical systems.
