Unit 1 Flashcards
Wave
Definition: a disturbance that carries energy from place to place
Mechanical Wave
Definition: matter that moves back and forth in a repeating pattern
Medium
Definition: the matter that a mechanical wave travels through
Model
Definition: a representation of a situation which makes important aspects easy to see
Wave Pulse
Definition: a single disturbance that doesn’t repeat
Wave Cycle
Definition: one complete motion of the repeating pattern in a wave
Transverse Wave
Definition: the matter moves in a pattern perpendicular to the direction the wave travels
Longitudinal Wave
Definition: the matter moves in a pattern parallel to the direction that the wave travels
Surface Wave
Definition: the matter moves in a circular pattern that is sometimes parallel and sometimes perpendicular to the direction the wave travels
Amplitude
Definition: is the size of the crests or troughs of a wave
Wavelength
Definition: the distance between the start of one wave cycle and the start of the next cycle
Frequency
Definition: the number of wave cycle that pass a certain point in a given period of time
Wave Speed
Definition: the distance a wave moves in a given amount of time
Wave Relationship
Definition: the equation that relates wave speed, frequency, and wavelength (wave speed = frequency x wavelength
Is A Wave Subjective?
No
Three Examples Of A Wave
- Sound
- Energy
- EM waves
