Question

Which sequence shows all the spectral colors of visible light arranged in an increasing order of their frequency? A. red, yellow, orange, blue, green, indigo, and violet B. red, orange, yellow, green, blue, indigo, and violet C. violet, indigo, blue, green, yellow, orange, and red D. violet, indigo, green, blue, orange, yellow, and red

Answer 1

Answer:

The answer is B. red, orange, yellow, green, blue, indigo, violet

Explanation:

Most textbooks have the acronym ROYGBV to express the order in which colors appear on the spectrum of light, indigo is included in your list, and that's not a problem, although it's not typical. This spectrum of light is the same order in which colors appear in rainbows.

Answer 2

Explanation:

There exists an inverse relationship between frequency and wavelength of a light. The wavelength of red color is maximum while the wavelength of violet light is least.

The reason behind maximum wavelength of red light is that it scatter the least.

Violet color - 380 - 450 nm

Blue - 450 - 495 nm

Green - 495 - 570 nm

Yellow - 570 - 590 nm

Orange - 590 - 690 nm

Red - 620 - 750 nm

Hence, the correct sequence for the increasing order of frequency is given by:

violet > indigo > blue > green > yellow > orange > red
