Unit 5 Flashcards
What is a Wave
A disturbance that transfers energy from one place to another
What are the 2 types of waves
Electromagnetic and Mechanical Waves
Transverse Waves
A wave that vibrates up and down or perpendicular to the motion of the wave
Compression Waves
A wave that vibrates parallel to the motion of the wave side to side
Origin
The middle line
Crest
Top of wave
Amplitude
Distance from top to origin or bottom to origin
Wavelength
Distance from crest to crest or trough to trough
Trough
Bottom of wave
Wave Frequency
How many times the wave goes up and down
Compression
Compressed part of Wave
Rarefaction
Uncompressed part of wave
Unit for wavelengths
Meters
Unit for frequency
Hertz
The equation for wave speed
Frequency(Hz)*Wavelength(M)=WaveSpeed(M/S)
Reflection
A wave that hits an object that does not absorb energy
Incoming wave is
incident
Outgoing wave is
reflection
Middle line is
normal
Specular reflection is
Uniformally
Diffuse reflection is
not uniformly
Refraction is a
change of direction because of a change in wave speed
This wave is called the
refracted wave
