Question | Answer |
what is a wave | a disterbance that transfer energy |
what is a medium | the meterial solid liquid or gas through which a wave can travel |
what is a transverse wave | when particles move perpendicularly to the direction the waves travel |
which part of the wave is the crest | the highest part of the wave |
which part of the wave is the trough | the lowest part of the wave |
what is a longitudinal wave | when the particles move back and forth |
which part of the wave is the compression | the strongest part of the wave |
which part of the wave is the rarefaction | the weakest part of the wave |
what is a mechanical wave | waves that require a medium |
what is a electromagnetic wave | a wave that does not require a medium |
what is amplitude | a measure of how far apart the particles are in a medium |
what is wave length | the length of the wave |
what is frequency | the amount of speed in a wave |
what is hertz | how you measure a wave |
what is wave speed | the speed of the wave |
what is force | a push or a pull exerted on an object in order to change the motion of the object |
what is work | the use of fore to move an object some distance |
what is power | the rate of how much work is done |
a 100n girl climbs a flight of stairs in 5 seconds. The stairs are 5m high, how much power did she generate? | 100watts |
a force of 40 newtons pushing an object 10 meters in the direction of the force | the force does 400 newton meters |
the frequency of a wave was 60 hertz and the wavelength was 10 cm find its speed | 600 cm/sec |
what type of waves dont need a medium | electromagnetic waves |
in a longitudinal/transverse wave particles move at right angles to the direction the wave travels | transverse wave |
how do you calculate speed | distance divided by time |
as the frequency increases the wavelength | decreases |
what is rest position | when the particles are in a displacement |
how do you calculate power | work divided by time |
