What are Waves?
A Disturbance that transfers energy
Wave
Wave where particles move back and forth
Longitudinal
Particles move perpendicularly to to the direction the wave travels.
Transverse Wave
A wave that requires a medium?
Mechanical Wave
Higher Frequency in terms of cycles means?
More cycles per second
Material through which a wave travels
Medium
Example of a longitudinal wave?
Sound
Would this wave create compression and rarefaction or crests and troughs?
Crests and Troughs
Example of a mechanical Wave?
sound
If the amplitude of a wave increases, what happens to its energy?
increases
Ocean waves use ......... as a medium.
Water
Longitudinal waves create ........ when sound waves are packed closely together. (Slinky bunched up)
Compression
The disturbance for this wave is ...... and .......
up and down.
Waves that do not require a medium?
Electromagnetic Waves
Formula to calculate wave speed?
Wave Speed = Wavelength / Wave Period
Highest point on a wave.
Crest
Longitudinal waves also create . ... ....... when sound is more spaced out. (slinky expanding)
rarefaction
Are transverse waves faster or slower than longitudinal waves?
Slower
Example of an EM wave?
x-rays
microwaves
visible light
UV light
radio
Formula to calculate Wavelength
Wavelength = Wave Speed / Frequency
Lowest Point of a wave
Trough
To create a wave, there must be a ........
Disturbance
What has a combination of Longitudinal waves and Transverse waves?
Earthquakes
Why is it possible to see light in space but not hear any sound?
Because there is not gas or air
Unit used to measure Frequency?
Hertz
