Longitudinal Wave
What is Type of Mechanical Wave Energy that moves in the SAME DIRECTION as the disturbance that caused it. (examples: slinky)
100
This is where the crest is located on a wave
What is the top of a wave
100
Let's talk about this fancy symbol: λ Known as lambda it is the sign for: ______ _____ To find λ divide ____ and _____
What is It is the sign for wave length Speed over time λ=s/t
100
Interference When waves ____ ____ and get __ _____ _____ way
What is When waves CROSS PATHS and get IN EACH OTHERS way
100
Energy and matter can not be
What is Created or destroyed
200
Transverse Wave
What is -A type of mechanical wave -Energy that moves perpendicular to the thing that caused it -Example (a whip or rope)
200
This is where the trough is located on a wave
What is the bottom of the wave
200
Speed = ____ / ____ Speed = ____ x _____
What is distance by time (d/t) Wave length times frequency (λ x f)
200
Can two waves be in the same place at the same time? The waves ____ _____ each other and ____ ____
What is Yes! they push through each other and keep going
200
Forms of energy
What is sounds light thermal chemical nuclear kinetic
300
Mechanical Waves
What is -Waves that transfer energy through matter -Types: Transverse and Longitudinal
300
Amplitude definition? Drawn as? Bigger Amplitude = ________ energy Smaller Amplitude = ________ energy
What is -how much energy the wave is carrying -hight of the wave Bigger amplitude is more energy Smaller amplitude is less energy
300
Frequency = _____/____
What is Frequency = speed over λ(fancy) f=s/ λ
300
Types of interference?
What is constructive and destructive
300
Disturbance
What is usually a vibration
400
T
What is -The amount of time it takes for one wave to pass -Equation T= seconds/waves -T=s/w
400
Wave length measurements!
What is -the distance from the top of the wave to the top of the next -Can also be measured from middle to middle or bottom to bottom
400
To find frequency you need: ______ of the wave ______ of the wave
What is To find frequency you need: speed of the wave length of the wave
400
Constructive Interference Two waves intersect and their ____ and ____ are ______ Thus the _______ add to each other and cause the waves to get ____
What is Two waves intersect and their CREST and TROUGHS are IN SYNC Thus the AMPLITUDES add to each other and cause the waves to get BIGGER
400

Frequency Definition
What is the number of waves that pass a fixed point during a certain period of time
500
Destructive Interference Waves come together and the ____ of ones lines up with the ___ of the other The ____ cancel out and the wave gets ____
What is Waves come together and the CREST of ones lines up with the TROUGH of the other The AMPLITUDES cancel out and the wave gets SMALLER
500
