February Flashcards
Wave
The transfer of energy without transferring matter
Crest
Highest point of the wave
Trough
Lowest
Amplitude
The distance from the resting point to the crest of a wave
Frequency
The number of waves fthat pass a given point in a set period of time
Wavelength
The distance from crest to crest or trough to trough
Period
Time for a complete cycle to pass a given point
Medium
Matter through which a a mechanical wave travels
Transverse
A wave in which the energy travels perpendicular
Electromagnetic
A wave that does not need a medium to travel through
Longitudinal
A wave in which the energy travels in the same direction as the disturbance
Compression
When the waves are pushed closer together
Rarefraction
The point in longitudinal wave where the matter is spaced farther apart
Reflection
When wave strike a surface and bounce back in another direction
V ~ velocity ~ speed
m/s
