MJHS 7 Unit 1
7th grade science waves and energy review
| Question | Answer |
|---|---|
| All waves carry this. | Energy |
| All waves are created by this. | Vibrations |
| Waves do NOT carry this. | Matter |
| This type of wave has crests and troughs. | Transverse |
| This type of wave's motion is perpendicular to energy motion. | Transverse |
| This type of waves has compressions and rarefactions. | Longitudinal |
| This type of wave's motion is parallel to energy motion. | Longitudinal |
| This is a measure of a wave's energy. | Amplitude |
| This can be measured on a transverse wave from the rest position to the top of a crest. | Amplitude |
| This property of waves is measured from crest to crest. | Wavelength |
| This property of waves is measured from rarefaction to rarefaction. | Wavelength |
| The number of waves that pass by in a given amount of time is this property of waves. | Frequency |
| Frequency is measured in these units. | Hertz |
| Hertz (Hz) is a unit of measurement of this. | Frequency |
| Wave speed is equal to frequency multiplied by | wavelength |
| Wave speed is measured in these units. | meters per second (m/s) |
| Wavelength is measured in these units. | Meters |
| You can shake a rope up and down and make this type of wave. | Transverse |
| You can slide a slinky back and forth and make this type of wave. | Longitudinal |
| If you drop a pebble in a puddle of water, you can observe this type of wave. | Surface |
| A surface wave creates this type of motion. | Circular |
| A powerful type of wave produced by the energy released during an earthquake is called this. | Seismic wave |
| Primary, secondary and surface are all types of this wave. | Seismic wave |
| By timing the arrival of different seismic waves, scientists can pinpoint the location of this. | Earthquake |
| Sound waves are this type of wave | Longitudinal |
| Sound waves require a medium and classify as this type of wave. | Mechanical |
| Amplitude is to loudness as frequency is to: | Pitch |
| Both amplitude and frequency are a measure of a wave's: | Energy |
| Very loud or very high pitched sounds can damage your: | Hearing |
| The speed of sound in air is about ___m/s | 340 |
| Sound travels fastest in this state of matter. | Solid |
| Does something that is very elastic transfer sound faster or slower? | Faster |
| The thin membrane in your ear that is the first to vibrate from sound waves entering is the: | Eardrum |
| The three tiny bones in the ear are called the: | Hammer, anvil and stirrup |
| Can sound travel in outer space? | No |
| Can humans hear sounds greater thatn 20,000 Hz? | No |
| Instruments produce music when parts of the instrument do this: | Vibrate |
| Light waves are also called this type of wave. | Electromagnetic |
| Electromagnetic waves travel as this type of wave. | Transverse |
| Light waves have which two parts? | Electric and magnetic |
| All electromagnetic waves are organized into this diagram. | Spectrum |
| Which waves have the biggest wavelength-radio or gamma waves? | Radio |
| All EM waves travel at this speed: _____ m/s | 300 million |
| All EM waves are unique because they have different wavelengths and | Frequencies |
| The only part of the spectrum that humans can see is this. | Visible light |
| Humans can be harmed by EM waves with a very high: | Frequency |
| This type of wave can be felt as heat. | Infrared |
| EM waves travel as a 2 part ________ wave. | Transverse |
| Can light travel through outer space? | Yes |
| EM waves are caused by vibrations in these: | Charged particles |
