To determine

Explain the colors in visible spectrum.

Answer to Problem 1RQ

The visible spectrum’s colors are $\underset{\_}{\text{red, orange,}\text{yellow, green, violet,}\text{and blue}}$.

Explanation of Solution

An electromagnetic spectrum’s portion, which is visible to eye, is known as visible spectrum.

The visible spectrum contains the band of colors, which can be obtained by dispersing the white into the prism.

Dispersion is separation process of white color light into various six colors, which is shown in Figure 22.2.

Refer Figure 22.2 in the textbook for the visible spectrum is obtained in the white screen.

From Figure 22.2, the colors are presented in this spectrum are red, yellow, orange, green, violet, and blue.

Conclusion:

Hence, the visible spectrum’s colors are $\underset{\_}{\text{red, orange,}\text{yellow, green, violet,}\text{and blue}}$.
