Mechanical Wave |
A disturbance in matter that carries energy from one place to another. |
|
|
Medium |
Solid, Liquid, or Gas |
|
|
3 Types of Mechanical Waves |
Transverse, Longtitude, Surface |
|
|
Transverse Wave |
A wave that causes a medium to vibrate at right angles to the direction in which the wave moves. |
|
|
Longtitude Waves |
A wave in which to vibration is parallel to the direction the wave moves. |
|
|
Surface Waves |
A wave that travels along a surface seperating two mediums. |
|
|
Wavelength |
The distance between two like points on the wave. |
|
|
Amplitude |
The height of the wave compared to the undisturbed state |
|
|
Crest |
The heighest point above the undisturbed state. |
|
|
Trough |
The lowest point below the undisturbed state. |
|
|
Period |
The amount of time required for one wavelength to pass. |
|
|
Frequency |
The number of waves passing in a given amount of time. |
|
|
Reflection |
Bouncing back of waves. |
|
|
Refraction |
Bending of light due to change in speed. |
|
|
Diffraction |
Bending of waves around the edge of a barrier. |
|
|
Radio Waves |
Low energy waves with long wavelengths. |
|
|
Microwaves |
Longer than radio, shorter that light and infrared. |
|
|
Infrered Waves |
Invisible electromagnetic waves that are detected as heat. |
|
|
Visble Light |
The portion of the elecrtomagnetic spectrum taht human eyes can detect. |
|
|
Ultraviolet Rays |
Can cause skin cancer and blidness in humans. |
|
|
X-Rays |
Used in medicine industry and astronomy. |
|
|
Gamma Rays |
Highest energy in frequency. |
