Waves Flashcards
What do waves transfer
Energy and information without transferring matter
What are the two types of wave
Transverse and longitudinal
Give examples of transverse waves
Any electromagnetic:
Light, radio, info-red, gamma rays
Give an example of a longitudinal wave
Sound waves
In traverse waves…..are…….to the direction of the wave travel
Vibrations
Perpendicular
What is the wave length
The distance from one wave crest to the next
What is the amplitude
The distance from the top of the crest to the middle line
Frequency is the number of….per….
Waves per Second
What is the unit of frequency
Hertz (KHz)
Give the two equations for waves
Speed = frequency x wavelength
Frequency = 1
-
period
The period is the time for one……….to pass in……
Complete wave
Seconds
In longitudinal waves, …….. are…… to the direction of the wave travel
Vibrations are parallel
