What are transverse waves formed of?
Crests/peaks and troughs
2 of 18
What are longitudinal waves formed of?
rarefractions and compressions
3 of 18
Which way is the movement going in transverse waves?
up and down
4 of 18
Which way is the movement going in longitudinal waves?
along it
5 of 18
Which way is the energy going in transverse waves?
along it
6 of 18
Which way is the energy going in longitudinal waves?
along it
7 of 18
What is a wavelength? units
the measurement between two identical points on the wave, in meters
8 of 18
What is frequency? units
the number of waves that pass per second, in hertz
9 of 18
What is amplitude?
the amount of energy in the wave/ how high the wave is
10 of 18
What is a oscillation?
one complete wave length

What is the electromagnetic Spectrum?
Itsa a range of wavelengths and frequencies.

13 of 18
What are the two things that electromagnetic waves have in common?
They are transverse waves and they travel at the same speed in a vacuum - speed of light
