waves
this is an assignment I have to do
| Question | Answer |
|---|---|
| what is a object that a wave goes through? | medium |
| what is a wave? | A disturbance of particles that transfer energy |
| what is force? | How much something weighs |
| What is the amount of energy used to move something? | work |
| What is the efficiency of how you do work ? | power |
| what is the highest part of a transverse wave? | crest |
| what is a trough? | the lowest part of a transverse wave |
| what is a longitudinal wave? | A wave that moves back and forth in the same direction as the wave |
| what is compression? | when particles in a longitudinal wave get close together |
| what is the part of a longitudinal wave that particles are apart? | rarefaction |
| what is a wave that moves up and down? | a transverse wave |
| what are mechanical waves? | waves that need a medium |
| what are electromagnetic waves? | waves that don't need a medium |
| how far particles move from their resting point? | amplitude |
| what is wavelength? | the distance between two identical points on a wave |
| what is frequency? | The number of waves that pass a single point on a wave |
| What is frequency measured in? | hertz (Hz) |
| what is the speed a wave travels at? | wave speed |
| if some one wants to move a box that is 5,000 newtons 10 meters away, how much work would be done? | 50,000 joules |
| If someone used 400 joules to move a pencil in 2 seconds, how much power was used? | 800 watts |
| if the wave speed is 4 m/s and the frequency is 2 seconds, than what is wave length? | 2 meters |
| is sound a longitudinal or transverse wave? | longitudinal |
| why can't you hear in space? | because there is no medium |
| what type of wave is light? | electromagnetic |
| what wave is an earthquake? | mechanical |
| what is a combination of a longitudinal and transverse waves? | a surface wave |
