Question

Match List-I with List-II

List-I (Type of radiation)	List-II (Wavelength)
(A) Red	(I) <400 nm
(B) Blue	(II) 450-500 nm
(C) Ultraviolet	(III) >760 nm
(D) Infrared	(IV) 620-760 nm

Choose the correct answer from the options given below

• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)
• (A) - (IV), (B) - (II), (C) - (I), (D) - (III)
• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)

Hint:

Remember the order of the electromagnetic spectrum by wavelength:
Ultraviolet (<400 nm) \( < \) Visible Light (400-760 nm) \( < \) Infrared (>760 nm).
Within visible light, Blue (450-500 nm) has a shorter wavelength than Red (620-760 nm).
