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  
🗑
