The phenomenon in which the phase velocity of a wave depends on its frequency is called dispersion. Sometimes the term chromatic dispersion is used for specificity to optics. ref. A medium having this common property may be termed a dispersive medium. This term is used in the field of optics to describe light and other electromagnetic waves. Dispersion in the same sense can apply to any […]
When white light from the sun enters the earth’s atmosphere, the light gets scattered. Here the light spreads in all directions through the dust particles, free water molecules and the molecules of the gases present in the atmosphere. This is called the scattering of light. Or in other words, we can say it is the […]
Reflection of Light The returning light from the surface of an object when the light is incident on it is called reflection of light. Or in other words, we can say it is the phenomenon of bouncing back light into the same medium by the smooth surface. Examples include a reflection by a plane mirror, glowing […]
