Flashcards in P12- Wave Properties Deck (11):
What is a transverse wave?
The vibrations move up and down or from side to side. All electromagnetic waves are transverse.
What is a Longitudinal wave?
Vibrations travel along springs. The oscillations are parallel to the direction the waves direction in which the waves transfer energy.
What is the amplitude of a wave?
The maximum displacement of a point on the wave from its undisturbed position.
What is frequency?
The number of waves passing a fixed point every second. It is measured in hertz.
How do you find the period of the wave?
Period T (seconds, s) = 1/frequency f
What is the wave speed?
The speed of the waves is the distance travelled by each wave every second through a medium
How do you find wave speed?
Wave speed v = frequency f X wavelength
How do you find speed?
Speed = distance/time taken
How are sound waves caused?
Sound waves are caused by vibrating objects. These are passed through the surrounding medium as a series of compressions and rarefactions.
What happen to sound in solids?
They are converted to vibrations in the solid until it travels through.
