Topic 4 -Waves Flashcards
What 2 types of waves are there
1) transverse waves
2) longitudinal waves
What are transverse waves
Waves that move in a direction at right angles perpendicular to the wave direction
What do transverse waves do
Causes the particles in the medium to vibrate at right angles (90°) perpendicular to the wave direction
Medium - substance the wave travels through
Perpendicular- lines that crosses each other at a 90° angle
What are longitudinal waves
A wave that oscillates parallel to the wave direction
What do longitudinal waves do
They vibrate parallel to the direction of the wave
What do waves transfer
transfer energy and information but do not transfer matter
What is an example of a transverse wave
Light or any electromagnetic waves and water waves
What is an example of a longitudinal wave
Sound waves
What are the two parts of a longitudinal wave called
Compressions and rarefactions
What are the two parts of a transverse wave called
Peaks and troughs
