Q.

Match List-I with List-II:

 

List-I

(EM-Wave)

 

List-II

(Wavelength Range)

A Infra-red (I) 10-3nm
B Ultraviolet (II) 400 nm to 1 nm
C X-rays (III) 1 mm to 700 nm
D Gamma rays (IV) 1 nm to 10-3 nm

 

Choose the correct answer from the options give below                 [2024]

1 (A)-(I), (B)-(III), (C)-(II), (D)-(IV)  
2 (A)-(IV), (B)-(III), (C)-(II), (D)-(I)  
3 (A)-(III), (B)-(II), (C)-(IV), (D)-(I)  
4 (A)-(II), (B)-(I), (C)-(IV), (D)-(III)  

Ans.

(3)       

 Infrared is the least energetic thus having biggest wavelength (λ) and gamma rays are most energetic thus having smallest wave length (λ).
