| Wave Movement |
| #1 |
Describe the direction of a transverse wave movement |
Perpendicular to the disturbance or Up and down/side to side from the disturbance |
| #2 |
Describe the direction of a longitudinal wave movement |
Parallel to the disturbance or front to back with the disturbance |
| #3 |
List an example of something with transverse wave movement and an example of something with longitudinal wave movement |
Transverse - Light or Rope; Longitudinal - Sound, Slinky or Spring |
| #4 |
What are the 4 parts of a transverse wave and tell how to identify them |
Crest - top of wave; Trough - bottom of wave; Wavelength - crest to crest; Amplitude - middle to top |
| #5 |
What are the 4 parts of longitudinal wave and tell how to identify them |
Compression - bunch; Rarefaction - spread out; Wavelength - middle of one compression to the next; Amplitude - how compressed |
| Sound, Light and Seismic Waves |
| #1 |
Sound is an example of a _______ wave with a _______ movement |
Mechanical; Longitudinal |
| #2 |
Light is an example of an _______ wave with a ________ movement |
Electromagnetic (EM); Transverse |
| #3 |
Which seismic wave type can travel through both liquids and solids |
Primary Wave (p-wave) |
| #4 |
Which seismic wave type can only travel through solids and not liquids |
Secondary Wave (s-wave) |
| #5 |
Sound, light and seismic are waves...so what do they have in common |
They are all created by a disturbance and THEY ALL TRANSFER ENERGY! |
| Wave Properties |
| #1 |
What is a wave property |
A part of a wave that can be identified and measured |
| #2 |
Name the properties of a wave that we can measure |
Amplitude, Wavelength, Frequency, Speed |
| #3 |
What does the amplitude of a wave tell us |
How much ENERGY it has (bigger amplitude = more energy and smaller amplitude = less energy) |
| #4 |
What does the wavelength of a wave tell us |
If it has high or low frequency (more spread = low frequency and more bunched = high frequency) |
| #5 |
What does frequency of a wave tell us |
The pitch (high or low sound) of the wave (higher frequency - higher pitch; lower frequency = lower pitch) |
| Waves and Speed |
| #1 |
Why does sound travel fastest through a solid |
A solids particles are closer together |
| #2 |
Rank seeing light, feeling sound and hearing sound from slowest to fastest |
Hearing sound, Feeling sound then Seeing Light |
| #3 |
What factor causes seeing light to be first and feeling sound to be second |
Medium - does it require one or not |
| #4 |
What factor causes feeling sound to be second and hearing sound the be thrid |
Density - is the medium solid, liquid or gas |
| #5 |
What causes waves to travel at different speeds |
Medium and Density (because some require mediums and mediums have different densities) |
