Check understanding
- Explains how a vibrating object creates regions of compression and rarefaction in air
- Explains why sound travels fastest in solids and cannot travel in a vacuum
- Describes how an echo is produced and gives a practical application (sonar, ultrasound)
- Explains what sound absorption means and why soft furnishings reduce echoes
“If your child heard an echo in a large empty hall, could they explain what causes the echo, why the same sound in a carpeted living room doesn’t echo, and what would happen to sound in outer space?”
