Waves Flashcards
What does a wave transfer
Energy
What are the two types of waves
Transverse and longitudinal
What is an example of a transverse wave and how does it travel
Examples
Any electromagnetic spectrum waves
S wave from an earthquake
It moves at a right angle to the waves direction of travel
What is an example of a longitudinal wave and how does it travel
Examples
Sound waves
P waves from an earthquake
Travels in the same direction of the wave
What is the frequency of a wave
The number of waves that pass a point per second
What is frequency measured in
Hertz, Hz
What is the amplitude
The maximum height of the wave from the middle to the crest or tough
What is the wavelength
The distance from a point of one wave to the same point on the next wave
What is the law of reflection
The angle of incident must equal the angle of reflection
How can waves be refracted
By changing speed as they pass from one medium to another
What happens when a wave refracts
They change direction and slow down moving towards the normal when they speed up
