Q2. Match List - I with List - II
List-I
(A) Microwave
(B) UV Rays
(C) X-Rays
(D) Gamma-Rays
List-II
(1) Radar System for Aircraft Navigation
(II) To study crystal structure
(III) Radioactive decay of Nucleus

Choose the correct answer from the options given below:
(a) (A)-(I), (B)-(IV), (C)-(II), (D)-(III)
(b) (A)-(II), (B)-(IV), (C)-(III), (D)-(I)
(c) (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
(d) (A)-(I), (B)-(II), (C)-(III), (D)-(IV)

FirstInTest · Accepted Answer

Correct answer: b. The question asks to match List-I (Electromagnetic Waves) with List-II (Their Applications). According to the provided solution, the correct mapping is (A)-(II), (B)-(IV), (C)-(III), (D)-(I). This implies: (A) Microwave is used (II) To study crystal structure. (This is generally incorrect; X-rays are typically used for crystal structure analysis like X-ray diffraction, while microwaves are primarily used in radar systems.) (B) UV Rays are used for (IV) Lasik eye surgery. (This is a correct application of UV rays.) (C) X-Rays are associated with (III) Radioactive decay of Nucleus. (This is generally incorrect; gamma rays are associated with radioactive decay, while X-rays are used for medical imaging and material analysis.) (D) Gamma-Rays are used in (I) Radar System for Aircraft Navigation. (This is generally incorrect; microwaves are used in radar systems.) While some pairings in option (b) are scientifically inaccurate based on common physics knowledge, the instruction is to provide the explanation for the given correct answer. Based on the solution's designation, option (b) is the intended correct match.
