Match List I with List II:
| List I | List II |
|---|---|
| A. < 20 Hz | I. Longitudinal waves |
| B. > 20000 Hz | II. Electromagnetic waves |
| C. X- rays | III. Infrasonic waves |
| D. Sound waves | IV. Ultrasonic waves |
Choose the correct answer from the options given below:
Solution
✅ Correct Option: 4
Frequencies below 20 Hz are infrasonic waves (III). Frequencies above 20000 Hz are ultrasonic waves (IV). X-rays are electromagnetic waves (II). Sound waves are longitudinal waves (I). So A-III, B-IV, C-II, D-I.
