waves
what are waves?
a disturbance involving the transfer of energy
list one type of mechanical waves
Transverse, longitudinal, surface
what is the high point of a wave called?
crest
explain a transverse wave
what is energy
ability to do work
The material a wave travels through
Medium
what type of waves moves at right angles?
Transverse
what is the low point of wave called?
trough
what is a crest
the high point of a transverse wave
True or false. Ocean waves are traversal waves. explain
false they are a combination of transverse and longitudinal
can a solid be a medium
explain how it is possible
what type of waves vibrates in the same direction as the wave moves?
Longitudinal
how do mechanical waves form?
energy that causes a vibration
true or false? The trough is the high point of a wave?
false, it is the lowest point of a wave
why is it important to know what a crest and trough are to a surfer?
It helps them to find the resting point and not get to high or to low on the wave and crash
what type of waves move in a circular motion
surface waves
waves that vibrate at right angles
transverse waves
list 3 mediums for waves
air, liquids, solids
A side to side and up and down motion is called?
vibration
name an animal that uses longitudinal waves to move.
caterpillar
why do surface waves move in a circular motion
because they consist of 2 types of wave movements
how do you know a wave is a mechanical wave?
it needs a medium to travel
list the parts of an longitudinal wave.
compression, rarefaction
Describe a plant or animal in which you can observe wave motion
fields of grass and a worm inching along
when fans do the "wave" at games, what kind of wave is that called?
traversal
