Waves Flashcards
What is the parts of a wave?
rest position displacement peak trough amplitude wavelength time period frequency
What’s the meaning of rest position?
the undisturbed position of particles or fields when they are not vibrating
Whats the meaning of displacement?
the distance that a certain point in the medium has moved from its rest position
What’s the meaning of peak?
the highest point above the rest position
What’s the meaning of trough?
the lowest point below the rest position
What’s the meaning of amplitude?
the maximum displacement of a point of a wave from its rest position
What’s the meaning of wavelength ?
distance covered by a full cycle of the wave, usually measured from peak to peak, or trough to trough
What’s the meaning of time period?
the time taken for a full cycle of the wave, usually measured from peak to peak, or trough to trough
What’s the meaning of frequency?
the number of waves passing a point each second
What’s frequency measured in?
frequency (f) is measured in hertz (Hz)
How is wave speed calculated?
wave speed = frequency × wavelength
