Question
Match the following with the correct response.
| 1. A moving disturbance | A. Mechanical waves |
| 2. Propagation require material medium | B. Oscillatory motion |
| 3. Particles vibrate perpendicular to the | C. Transverse waves direction of wave propagation |
| 4. Back and forth motion | D. Wave |
- 1-B, 2-D, 3-A, 4-C
- 1-A, 2-C, 3-B, 4-D
- 1-D, 2-A, 3-C, 4-B
- 1-C, 2-B, 3-D, 4-A
Hint:
Wave is a moving disturbance and is of two basic types: mechanical and non mechanical
The correct answer is: 1-D, 2-A, 3-C, 4-B
Transverse waves do not require medium to travel whereas longitudinal waves require one. Transverse waves propagate perpendicular to wave motion.
