Question | Answer |
Wave | A disturbance that transfers energy |
Medium | The material - Solid, liquid, or gas - through which a wave can travel |
Transverse wave | In a transverse wave, particles move perpendicular to the direction the wave travels |
Crest | The point were the wave is at its highset |
Trough | The lowest point in a wave |
Longitudinal Wave | Particles move back and forth in the same direction that the wave travels. |
Compression | When a longitudinal wave closes in on itself |
Rarefaction | When a longitudinal wave spreads apart |
Mechanical Waves | Waves that require a medum |
Electromagnetic Waves | Waves that do not disturb a physical medium |
Amplitudes | How far particles move in the medium from their rest position. |
Wavelength | The distance from any point to the next identical point in the same wave |
Frequency | The number of waves that pass through a point in a given amount of time |
Wave speed | The speed that waves travel |
Hertz (Hz) | A unit of measurement used to measure frequency |
Force | A push or pull exerted on an object |
Work | The use of force used to move an object some distance |
Power | The rate of work that is being done |
Joe pushes a box with 50 N of force for 50 meters how much work does he do? | 2500 N |
Chuck pulls a wagon with 2500 N of force for 50 seconds how much power did he use? | 50 Joules |
What is the formula for work? | Work = Force x Distance |
What is the formula for power? | Power = Work / Time |
What is the formula for wave speed? | Wave Speed = Distance / Time |
A wave traveled 50 meters in 2.5 seconds. What is its speed? | 20 Hertz |
What is the highest point in a wave? | Crest |
What does a sound wave travel best through? Gas, solid, or liquid. | Solid |
