Waves Flashcards
What are the two types of waves?
Longitudinal, Transverse
What are some examples of longitudinal waves?
Sound waves
What are some examples of transverse waves?
Water waves, light waves
Transverse waves have oscillations ………. to the direction the wave travels in
perpendicular/at a right angle
Longitudinal waves have oscillations ………. to the direction the wave travels in
parallel/in the same direction
What is the highest point of a wave called?
Peak/crest
What is the lowest point of a wave called?
Trough
What is the centre line of wave called?
Equilibrium
What is the distance between a peak or a trough (from the equilibrium) called?
Amplitude
What is the name for the space from wither a peak to a peak or a trough to a trough called?
Wave length (λ)
What is the frequency of a wave?
How many waves occur over a period of time
What is the displacement of a wave?
How far a point on the wave is from the equilibrium.
What is a wave?
(1) A wave is a moving oscillation about a fixed equilibrium.
(2) A wave is a method to transfer energy.
What is wave speed?
The speed at which a wave moves away from its source (propagates)
