| List-I | List-II | ||
| (Colour) | (Wavelength range) | ||
| (A) | Yellow | (I) | 450 nm- 500 nm |
| (B) | Red | (II) | 550 nm- 600 nm |
| (C) | Blue | (III) | 650 nm- 700 nm |
| (D) | Green | (IV) | 500 nm- 550 nm |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (II), (B) - (III), (C) - (I), (D) - (IV)
Visible light runs from about 400 nm (violet) to about 700 nm (red), in the order of VIBGYOR: the wavelength increases from violet through blue, green and yellow to red.
(A) Yellow — this matches (II) 550 nm- 600 nm. Yellow lies between green and red.
(B) Red — this matches (III) 650 nm- 700 nm. Red has the longest wavelength of the four colours.
(C) Blue — this matches (I) 450 nm- 500 nm. Blue has the shortest wavelength of the four colours.
(D) Green — this matches (IV) 500 nm- 550 nm. Green lies between blue and yellow.
