Type of wave that doesn't need a medium
Type of wave the does need a medium
A mechanical wave ________ travel forever
A mechanical wave loses ________ as it travels
A Mechanical wave travels faster in __________ materials
Describe the direction of a transverse wave movement
Describe the direction of a longitudinal wave movement
List an example of something with transverse wave movement and an example of something with longitudinal wave movement
What are the 4 parts of a transverse wave and tell how to identify them
What are the 4 parts of longitudinal wave and tell how to identify them
Sound is an example of a _______ wave with a _______ movement
Light is an example of an _______ wave with a ________ movement
Which seismic wave type can travel through both liquids and solids
Which seismic wave type can only travel through solids and not liquids
Sound, light and seismic are waves...so what do they have in common
What is a wave property
Name the properties of a wave that we can measure
What does the amplitude of a wave tell us
What does the wavelength of a wave tell us
What does frequency of a wave tell us
Why does sound travel fastest through a solid
Rank seeing light, feeling sound and hearing sound from slowest to fastest
What factor causes seeing light to be first and feeling sound to be second
What factor causes feeling sound to be second and hearing sound the be thrid
What causes waves to travel at different speeds
Electromagnetic (EM)
Mechanical
CANNOT
ENERGY
DENSER
Perpendicular to the disturbance or Up and down/side to side from the disturbance
Parallel to the disturbance or front to back with the disturbance
Transverse - Light or Rope; Longitudinal - Sound, Slinky or Spring
Crest - top of wave; Trough - bottom of wave; Wavelength - crest to crest; Amplitude - middle to top
Compression - bunch; Rarefaction - spread out; Wavelength - middle of one compression to the next; Amplitude - how compressed
Mechanical; Longitudinal
Electromagnetic (EM); Transverse
Primary Wave (p-wave)
Secondary Wave (s-wave)
They are all created by a disturbance and THEY ALL TRANSFER ENERGY!
A part of a wave that can be identified and measured
Amplitude, Wavelength, Frequency, Speed
How much ENERGY it has (bigger amplitude = more energy and smaller amplitude = less energy)
If it has high or low frequency (more spread = low frequency and more bunched = high frequency)
The pitch (high or low sound) of the wave (higher frequency - higher pitch; lower frequency = lower pitch)
A solids particles are closer together
Hearing sound, Feeling sound then Seeing Light
Medium - does it require one or not
Density - is the medium solid, liquid or gas
Medium and Density (because some require mediums and mediums have different densities)
