P6-waves Flashcards
What is the trough
The lowest point of a wave
What is the crest
The highest point of a wave
What is amplitude
Distance between highest or lowest point to the middle line
What is wavelength
Distance between each wave
What are transverse waves
Oscillations are perpendicular to the direction of energy transferred
What are longitudinal waves
The oscillations are parallel to the direction of entry transfer
What is equation to work out wave speed
Frequency x wavelength
