# Wave Unit Test

Question | Answer |
---|---|

What is the definition of a wave? | A disturbance that transfers energy that travels through a medium |

What is a medium? | The material (solid, liquid ,gas) which a wave can travel through |

Transverse wave? | A wave where particles move perpendicular to the direction the wave travels |

What is a crest? | The highest part of a wave |

What is the definition of a trough? | The lowest part of a wave |

What is a Longitudinal wave? | Particles that move back and forth compared to the direction the wave is moving |

What is Compression? | The strongest part of a wave |

What is Rarefaction | The weakest part of a wave |

What is a Mechanical wave? | A wave that requires a medium |

What are Electromagnetic waves? | A wave that does not travel through a medium |

What is Amplitude? | A measure of how particles in the medium move from the resting place. |

What are Wavelengths? | The distance from any point of a wave to the next identical wave. |

What is Frequency? | The number of that pass a point at a given time. |

What are Hertz? | The unit of measure of frequency. |

Longitudinal waves move (perpendicular, parallel) compared to the direction the wave is moving | parallel |

What is Power? | The rate at which work id done |

Jake's car went a total of 75 meters in a total of 5 minutes. What is the total speed? | Speed: 15 mpm |

If the distance is a total of 28 meters and the time is 7 minutes, what is the total speed? | Speed: 4 mpm |

If there is a force of 4 newtons and a distance of 3 meters, what is the amount of work? | Work: 12 j |

If the force is 10 newtons and the distance of 5 meters, what is the total amount of work? | Work: 50 j |

True or false: The particles in a transverse wave move parallel? | False; The particles in a traverse wave move perpendicular |

If the amplitude is high, then the wave has a (high, low) frequency? | high |

True or false: There is only one formula for speed; Distance/Time | False; Distance/Time, Wavelength X Frequency |

Define Work and name it's formula | Using a force to move an object a distance. Formula: Force X Distance |

Define Force and name it's formula | something that causes a change of motion is an object. Formula: N x M= J |
