Longitudinal and transverse waves

Includes amplitude frequency and wavelength

What do waves do?

they transfer energy from one place to another without transferring matter (atoms)

Transverse - definition

Vibrate at 90 degrees to the direction of energy transfer

what wave vibrates at 90 degrees to the direction of energy transfer?

transverse

what are some examples of transverse waves?

light, water, radio, infa red, uv

longitudinal waves - definition

Vibrate parallel to the direction of energy transfer

what wave vibrates parallel to the direction of energy transfer

longitudinal

what are some examples of longitudinal waves

sound, ultrasound and ultrasonic

label the diagram

Rest line, peak/crest, wavelength, negative amplitude, trough, positive amplitude

Amplitude - definition

the height the wave from the rest line

Wavelength - definition

the length of one wave

Frequency - definition

Number of waves produced per second
