| List\(-I\) | List\(-II\) |
| \(UV\) rays | \((i)\) Diagnostic tool in medicine |
| \(X-\) rays | \((ii)\) Water purification |
| Microwave | \((iii)\) Communication, Radar |
| Infrared wave | \((iv)\) Improving visibility in foggy days |
Pick an option to check your answer.
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
