Wave
A repeating disturbance or movement that moves energy through matter or space.
Medium
The matter(solid, liquid , gas) that mechanical waves travel through
Mechanical Waves
Transverse and Longitude
Categories of waves
Mechanical and Electromagnetic
Transverse Wave
Energy in the medium moves back and forth at right angles to the direction the wave travels
Longitudinal/compressional
Energy moves back and forth the same direction that the wave travels
Electromagnetic waves
Do not need a medium to travel through in order to transfer energy
Crest
Highest point in a transverse wave
Trough
Lowest point in a transverse wave
Wavelength of transverse wave
Distance from one point of a wave to the nearest point just like it
Frequency
the number of wavelengths that pass a fixed point each second
Amplitude
Distance between a crest or trough and the position of the medium at rest
if wave length increases…
Then the frequency decreases
Compression
An area where the wave from distance from one point of a wave ti the nearest point
The greater the amplitude…
The more energy the wave carries
If you increase the amplitude of a compressional wave…
The volume gets louder
Reflection
The process by which a wave hits an object and bounces off of it
Absorption
When a wave hits a material and it is not reflected back
Transmission
