What is the term for the band of colours produced when light is dispersed?

Correct option is C

The correct answer is (C) Spectrum.

Explanation:

• A spectrum refers to the band of colors that is produced when light is dispersed, typically through a prism or other dispersing mediums. The spectrum consists of different colors that include red, orange, yellow, green, blue, indigo, and violet in the case of visible light.

Information Booster:

• The phenomenon of light dispersion is called refraction, where light bends as it passes through different mediums, separating the colors in the process.
• A spectrum can be observed not only with visible light but also with other forms of electromagnetic radiation, like radio waves, microwaves, or x-rays.
• Newton is credited with the discovery of the visible spectrum of light through a prism in 1666.

Additional Information:

• Absorption: When light is absorbed by a substance and not reflected or transmitted.
• Refraction: The bending of light as it passes through different media.
• Reflection: When light bounces off a surface rather than passing through or being absorbed.
