- When vibration stops, sound stops.
- Vibratory motion means oscillatory motion with change in shape.
- Sound needs a medium to travel.
- Sound cannot travel through a vacuum.
- Sound travels in solids, liquids, and gases.
- Sound wave in air is a longitudinal wave.
- Particles of air vibrate along the direction of sound travel.
- Compression is a region where particles move towards a point.
Common Mistakes to Avoid
