science - waves/transverse and longitudinal Flashcards
what does ampitude mean
The measurement of how tall a wave is from the resting position to the peak
what does frequency mean
how many waves pass a certain point per second.
what does peak mean
The highest point in a wave.
what does trough mean
The lowest point in a wave.
what does rarefraction mean
when the particle in a wave are spread out
what does compression mean
when the particles in a wave are compressed together
what does wave length mean
the distance from one wave to the other
what are the two types of wave
transverse and longitudinal
what is an example of a longitudinal wave
slinky,sound
what is an example of a transverse wave
ripples in water, light
what is the difference between transverse and longitudinal waves?
transverse waves cause the medium to move PERPENDICULAR (up and down) to the direction of the wave. Longitudinal waves cause the medium to move PARALLEL (left and right) to the direction of the wave.
what does medium mean
a substance that can transmit energy
True or false a wave transfers matter
a wave always transfers energy without transferring matter
what happens when light enters a more dense medium
it will slow down
what happens when a wave speeds up
when a wave speeds up it will bend away from the medium
what happens when light enters a less dense medium
it will speed up
what happens when it enters at an angle
it will change direction
what happens when a wave slows down
when a wave slows down it will bend towards the medium
what type of wave is a longitudinal wave
Mechanical
what type of wave is a transverse wave
electromagnetic
