Note: Students should understand the phenomenon of dispersion of white light in its constituent colours. The spectrum of the sunshine source has each wavelength. BIV is a handy reminder for the color sequence that makes up the rainbow: red, orange, yellow, green, blue, indigo and violet. Most of the sunshine sources produce light at different wavelengths. Here are the seven colors of the rainbow and what each color symbolizes.

As the wavelength is within the visible region then it is called visible light. Hence, the correct option is A, i.e., True.Įlectromagnetic radiation is often described through its frequency and wavelength. Rainbows have seven colours because water droplets work like a prism and split white sunlight into the seven colours of the spectrum (red, orange, yellow, green, blue, indigo, violet). Sunlight can be understood as visible or white light and it is the combination of all visible colours. The white light is a combination of various colours where every colour can be connected with a particular wavelength of light. The abbreviation of VIBGYOR is red, orange, yellow, green, blue, indigo, and violet. These are clean spectral colours namely VIBGYOR. Red is listed first because it is the first color in the rainbow’s arc. There are different colours of light that correspond with narrow wavelength bands. The Colors of the Rainbow and Their Meanings 1. The human eye detects the colour in the range of wavelengths from 400nm to 700nm which is called a visible spectrum of visible light. The colour sensation can be determined by the light spectrum which arrives at the human eye.

Rainbows appear in seven colours after dispersion of white light in its constituent colours. There are different categories of colours in visible light like red, orange, yellow, green, blue, indigo and violet. Hint: The observable region in the electromagnetic spectrum is called visible light.
