Answer & Solution
Correct Answer
(B) \((a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)\)
Step-by-step Solution
Detailed explanation
\(uv\) rays - used for water purification \(X-\)rays used for diagnosing fracture Microwaves are used for mobile and radar communication Infrared waves show less scattering therefore used in foggy days
