Question

Match Column-1 with Column-2. In the table given below, certain EM waves are listed in Column-1 and their uses in Column-2 not necessarily in that order.

Choose the correct matching of waves and their uses from the options given below:

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

Answer 1

The Correct Option is C

Here is the correct matching of the electromagnetic waves with their uses:
1. Microwaves are used in RADAR systems, so (A) matches with (III).
2. Ultraviolet rays are used in water purification, so (B) matches with (IV).
3. X-rays are used in medical diagnostics, so (C) matches with (I).
4. Infrared rays are used for night vision, so (D) matches with (II).
Thus, the correct matching is:
(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
