- A(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
- B(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
- C(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
- D(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
Correct answer
B. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
Step-by-step solution
The electromagnetic spectrum consists of various waves with characteristic wavelength ranges: Radio waves have the longest wavelengths, typically > 0.1 m (order of 10² m ). Visible light ranges from 400 nm to 700 nm , which is of the order of 10⁻⁶ m . X-rays have wavelengths in the range of 10⁻⁸ m to 10⁻¹³ m (order of 10⁻¹⁰ m ). Gamma rays have the shortest wavelengths, typically Thus, the correct matching is (A)-(I), (B)-(II), (C)-(III), (D)-(IV). Answer: (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
