Waves Flashcards
What is the source of a wave
A vibration or an oscillation
Where do waves transfer energy
From one point to another
How do waves transfer energy
They transfer energy without transferring the particles
How do transverse waves move
They travel perpendicular to the direction of vibration of the medium
Example of transverse waves
-EM waves
-Water waves
How do longitudinal waves move
They travel parallel to the direction of vibration of the medium
Example of longitudinal waves
Sound waves (only)
What is the highest point of a transverse wave called
Peak/Crest
What is the lowest point of a transverse wave called
Trough
What is amplitude
The amplitude of a wave is the maximum possible displacement of a point from its rest position
What is wavelength
The wavelength of a wave is the shortest distance between any two points in phase
What is period
The period of a wave is the time taken to produce one complete wave
What is frequency
The frequency of a wave is the number of complete waves produced per second
Formula for frequency, SI unit
f = 1/T
Frequency = 1/Period
SI unit: Hertz (Hz)
Formula for velocity of a wave
v = f(,l)
wave speed = frequency x wavelength
