physics- water waves Flashcards
what are water waves?
undulations or ripples
how do water waves travel through water?
with a transverse motion
what can they be reflected from?
surfaces
what happens when waves meet?
they ad or cancel out, something called superposition
what are undulations?
the up and down movement in waves
which way do the undulations move through the water?
at 90% to the direction of travel
what is an example of undulation?
standing still in the sea and feeling the water rise and descend on your leg
what can water waves do off a surface?
reflect
what is and example of reflection?
when waves at sea are reflected when they hit the harbour wall
what happens when two waves meet each other in step?
they add together and reinforce each other
what happens when two waves meet each other out of step?
they cancel out
