Parts of a Wave
the top of the wave
Crest
This type of mechanical wave is described by the parallel back and forth motion of the medium
Longitudinal
When a wave bounces off a medium
Reflection
What is the wave speed equation
velocity = wavelength (frequency)
A repeating disturbance or pulse that transfers energy
Wave
The bottom of the wave
trough
This type of wave does not require a medium to travel
Electromagnetic Waves
The bending of a wave due to a change in mediums
Refraction
What is the equation when solving for frequency?
frequency = velocity / wavelength
When a crest and a trough interfere what kind of interference is this?
Destructive Interference
Distance from crest to crest
Wavelength
This type of wave requires a medium to travel
Mechanical : Transverse / Longitudinal
When a pencil looks bent in water this is an example of....
Refraction
If a guitar string has a frequency of 400 Hz and has a wavelength of 0.4 m when played, what is the wave speed?
160 m/s
When 2 crests interact what kind of wave Interference is this?
Constructive Interference
Distance from rest to crest
Amplitude
What are the two types of Mechanical Waves
Transverse Longitudinal
When a wave hits a medium and bends around it
Diffraction
A wave with a speed of 3,000,000 m/s and a wavelength of 6,000,000 m, What is the frequency?
0.5 Hz
State the law of reflection
Number of waves per cycle
Frequency
List 3 types of electromagnetic waves
radio, micro, infrared, visible light, ultraviolet, X-ray, Gamma
When waves vibrate at the same frequency, sometimes strong enough to break the glass
Resonance
A tidal wave is traveling at 500 m/s with a frequency of 150 Hz what is the wavelength?
3.125 m
List three types of mediums for a wave to travel
Water, air, solids, etc
