Question

(3) The order of wavelength of red, yellow and orange is
(a) Yellow < orange < red
(b) yellow > orange > red
(c) Orange > red > yellow
(d) none of above​

Answer 1

Answer:

(a)

red has high wavelength thus red in colour, orange light coloured than red so less wavelength than red and yellow is lightest

Answer 2

The order of a wavelength of red, yellow, and orange is Option (a) Yellow < orange < red.

Explanation:

Different wavelengths make up visible light waves. The wavelength of visible light determines its color.

• Red has a wavelength of 780-622, Orange has a wavelength of 622-597, whereas Yellow has a wavelength of 597-577.

• The visible spectrum of light is the order of colors in light, sorted from shortest to longest wavelength. However, light waves can have wavelengths that are shorter or longer than those in the visible spectrum, and many common kinds of radiation are just light waves with different wavelengths.
