Worked practice questions
Why are ultrasonic waves useful over long sonar paths?
- Not easily absorbed
- Strongly absorbed
- Wide-beam travel
- Short travel range
Show answer and solution
Correct answer: A. Not easily absorbed
Ultrasonic waves are not easily absorbed, so they can travel a long distance in sonar.
When does a swing reach resonance under repeated pushes?
- Infinite damping
- At natural interval
- No push is applied
- Random push timing
Show answer and solution
Correct answer: B. At natural interval
The swing’s amplitude grows when periodic pushes match its natural interval.
