Features Of Waves Flashcards
What is the crest of a wave
The top of the wave
What is the trough of a wave
The bottom of the wave
What is the wavelength
The distance between two of the same points on the wave
What is wavelength measured in
Metres (m)
What is the amplitude of a wave
How high the wave is above the resting point.
What is the frequency of a wave
The number of waves in 1 second.
What are the units for frequency of a wave
Hertz (Hz)
What are the two types of wave
Longitudinal and transverse waves
What are transverse waves
The oscillations are at right angles to the direction of travel (they go up and down)
What are longitudinal waves
The oscillations are along the same direction as the direction of travel (they go back and forth)
What type of wave is light
Transverse wave
What is the angle of insidence equal to
Angle of reflection
What is geostationary
Stays in the same position all the time
What is geosynchronous
Has an orbit time of 24 hours
What is used to send satellites information
Microwaves because they can travel through the atmosphere
