Waves

Amplitude

Amplitude

is the distance from the equilibrium position to the maximum displacement

Wavelength

is the distance between a point on one wave to the same point on the next wave

Frequency

is the number of waves that pass a single point per second

Speed

is the distance travelled by a wave each second

Crest

is the highest point on a wave above the equilibrium ,or rest ,position

Trough

is the lowest point on a wave below the equilibrium ,or rest , position

Electromagnetic spectrum

are transverse waves that transfer energy from the source of the waves to an absorber

Speed of electromagnetic waves

3.0 time 10 to the power 8 m/s
