Match List-I with List-II regarding the typical wavelength ranges of electromagnetic waves. List-I List-II (A) AM Radio waves (I) > 0.1 m (B) Microwaves (II) 0.1 m to 10⁻³ m (C) X-rays (III) 10⁻⁹ m to 10⁻¹² m (D) Gamma rays (IV) Choose the correct answer from the options given below:
Options
- A(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
- B(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
- C(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
- D(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
Correct answer
D. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
Step-by-step solution
According to the standard electromagnetic spectrum: AM Radio waves have the longest wavelengths, typically > 0.1 m . Microwaves fall in the range of 0.1 m to 1 mm ( 10⁻³ m ). X-rays have much shorter wavelengths, ranging from 1 nm ( 10⁻⁹ m ) to 10⁻³ nm ( 10⁻¹² m ). Gamma rays have the shortest wavelengths, typically Therefore, the correct matching is (A)-(I), (B)-(II), (C)-(III), (D)-(IV). Answer: (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
