Waves Flashcards
What best summarises the Laws of Reflection for waves?
The angle of incidence is equal to the angle of reflection
What can waves travel through?
Air, liquids, solids and the vacuum of space
What can waves be described as?
An oscillation that travels through space or matter, accompanied by a transfer of energy
Do mechanical waves require a medium?
Yes
Do non-mechanical waves require a medium?
No
What is an example of a mechanical wave?
Sound
What is an example of a non-mechanical wave?
Electromagnetic radiation
What does wave motion transfer?
Energy from one point to another, often with no transfer of the material of the medium
What do particles in longitudinal waves do?
Vibrate back and forth, so the direction of their movement is parallel to the direction of the wave
What is an example of a longitudinal wave?
Sound waves
What is an example of a transverse wave?
Ocean waves
What do particles in transverse waves do?
Vibrate up and down or left and right, so that the direction of the movement is perpendicular to the direction of the wave
What are sections that are pushed together in longitudinal waves called?
Compressions
What are sections that are stretched out in longitudinal waves called?
Rarefactions
What is the high point of a transverse wave called?
Crest
