Question | Answer |
What is a Wave? | A wave is a disturbance that transfers energy. |
What is a Transverse Wave? Give an example of something that can make this kind of wave. | A transverse wave is a wave that moves perpendicularly(up and down) to the direction the wave travels. An example is if you move the end of a slinky up and down. |
The Crest is the highest point on the wave?True or False | True |
What is a Medium? | The material through which a wave can pass(solid, liquid, or gas). |
The Trough is the measure of how far particles in the medium move from their rest position.True or False | False. The trough is the lowest point on a wave. |
Give an example of a Longitudinal Wave. | One example: When sound waves pass through the air, the air moves back and forth in the same direction that the sound wave travels. |
a 200 Newton boy rides a bicycle 5.5 meters forward and then stops to turn onto a street. How much work has he done? | 200(5.5)=1,100 The boy has done 1,100 Joules of work |
A women does 6,500 Joules of work in 4 minutes. how much power has she used. | 6,500/240=27.08 Watts |
Is Compression the act of being squished or spread apart? | The act of being squished. |
What are waves that require a Medium? | Mechanical Waves |
what are Vibrations of electric and magnetic fields called. | Electromagnetic Waves |
a wave has a frequency of 75 Hz and a wavelength of 15 m. what is the speed of the wave. | the speed of the wave is 1,125 m/s |
is Rarefaction the act of being squished or spread apart? | the act of being spread apart. |
The measure of how far particles in the medium move from their rest position. | Amplitude |
The distance from an point on a wave to the next identical point on the same wave. | Wavelength |
What is Frequency? | the number of waves that pass a point in a given amount of time, usually one second. |
What is equal to one wave length per second? | Hertz |
what is the Speed that waves travel called? | Wave Speed |
What is a push or a pull exerted on an object in order to change the motion of the object called? and what's it measured in? | Force. Its measured in newtons |
what is the use of force to move an object some distance called? and what is it measured in? | Work and its measured in Joules |
What is power? | The rate at which work is done. |
A kid tried to push a car but it didn't work, how much work was done? | none |
what is the formula for work? | force(distance) |
what is power measured in? | Watts |
If a wave goes up 7 cm above the resting point and goes 7 cm below the resting point how many cm from the resting point is the trough? | 7 cm |
a bright light shined into a students eyes, what waves does the light travel through? | Transverse Wave |
