Question

When white light passes through a prism, the prism separates the light into different colors. What are all these colors together called? A) energy B) intensity C) spectrum D) wavelengths

Answer 1

The colors together coming out of a prism is called: C) Spectrum

Answer 2

Answer: The correct answer is Option C.

Step-by-step explanation:

White light consist of seven colors. These colors are visible when a white light is passed through a medium having different refractive index.

The colors are Red, Orange, Yellow, Green, Blue, Indigo and Violet.

The splitting of white light into seven colors is known as dispersion and the colors together are known as spectrum.

The color having highest frequency and lowest wavelength is red and the color having lowest frequency and highest wavelength is violet.

The order of highest frequency to lowest frequency of the colors follows:

`\text{Red}>\text{Orange}>\text{Yellow}>\text{Green}>\text{Blue}>\text{Indigo}>\text{Violet}`

Hence, the correct answer is Option C.
