Progressive Waves Flashcards
What is a progressive wave?
A moving wave that carries energy from one place to another without transferring any material
What is reflection?
The wave is bounced back when it hits a boundary.
What is refraction?
The wave changed direction as it enters a different medium. The wave slows down or speeds up.
What is diffraction?
The wave spreads out as it passes through a gap or round a corner.
What is displacement?
How far a point on a wave has moved from its undisturbed position.
What is amplitude?
The maximum magnitude of the displacement. Crests and Troughs.
What is wavelength?
The length of one whole wave.
What is a period?
The time taken for one whole wave cycle.
What is frequency?
The number of whole wave cycles per second passing a given point.
What is phase?
A measurement of the position of a certain point along the wave cycle.
What is phase difference?
How much one wave lags behind the other.
What is the formula that involved frequency and period?
frequency=1/period
What is the formula for wavespeed?
wavespeed=frequency x wavelength
