QuestionAnswer
What are results from vibrations from medians called? Waves
What is the solid, liquid or gas that waves can travel through called? Mediums
Which wave's particle's move perpendicularly to the direction the wave travels? Transverse wave
What is the point where the wave is highest called? Crest
What is the lowest point on a wave called? Trough
Which wave's particle's move parallel to the wave? Longitudinal Wave
What are the parts of the wave that are closest together called? Compression
What parts of the wave are furthest apart called? Rarefaction
Which waves require a medium to be able to travel? Mechanical waves
Which waves can travel without a medium? Electromagnetic
What is the measure of how far particles in the medium move from their rest position? Amplitude
What is the distance from crest to crest or trough to trough called? Wavelength
What is the number of waves that pass a point in a given amount of time called? Frequency
What is frequency measured in? Hertz
What are the speeds that waves travel called? Wave speed
What is a push or pull exerted on an object in order to change the object's motion called? Force
What is the use of force to move an object some distance called? Work
What is the rate at which work is done? Power
What is the equation for work? Work=Force x Distance
What the equation for power? Power=Work/Time
Carly used 10 newtons to push a box 5 meters. How much work did she complete? 50 Joules

In a longitudinal wave, you can measure the wavelength from ________ to ________ or ________ to ________ rarefaction to rarefaction or compression to compression/compression to compression to rarefaction to rarefaction
High frequency waves have ________(shorter or longer) wavelengths than low frequency wavelengths. Shorter
When calculating equations with distance, what do you measure them in? Meters
