What are Waves
Waves: disturbance that transfers {blank} from one place to another
Energy
Particles of the matter in the medium vibrate (blank) or in the same direction of wave motion
parallel
How do you measure the wavelength in a transverse wave?
The distance from one crest to the next crest
A sound wave can be classified as a _____ wave.
Longitudinal wave
I'm in a boat, and a large wave is heading my way. Will I just sit there and bob up and down, and not be carried towards the shore?
Yes or No?
Yes. You will not be moved towards the shore because waves can not move matter.
What do mechanical waves NOT transfer?
Matter (Solid, Liquid, Gas)
True or False:
Sound CAN travel through space
False:
It CANNOT
What is the amplitude of a transverse wave?
The highest point
What is impossible to transmit a sound wave?
outer space (a vacuum)
What waves are created by earthquakes?
seismic waves
material a wave can travel through
Medium (Solid, Liquid, or Gas)
What is the rarefaction?
Low pressure area on a longitudinal wave.
How do you measure the frequency of a wave?
It's the number of crests that pass a certain point in a given amount of time.
can LIGHT waves travel through space?
YES! They don't need a medium to travel!
If I tie a rope to a tree and start moving it up and down, creating a formation of a transverse wave. What is the medium for this wave motion?
The rope
True or False:
Energy is NOT a medium
True
Disturbance is (blank) to the direction of the wave
perpendicular
True or False?
Electromagnetic waves need a medium to travel.
FALSE!
They can travel through a medium as well as empty space. So, they dont NEED a medium in order to travel!
Which wave travels the fastest? a sound wave or a light wave?
a light wave travels the fastest!
lighting always comes before thunder!
What are the two types of a mechanical wave?
Transverse and Longitudinal
the change in pressure between the rarefaction and compression
The higher the amplitude, the more (blank) the wave has.
the more energy the wave has.
Which factor effects the speed on the wave?
a. the medium the wave travels through.
b. the reflection of the wave.
c. the transmission of the wave.
d. the amplitude of the wave.
A. The medium the travel travels through.
What population is in the MOST danger for damage caused by an earthquake?
A population living near an active fault zone!
Remember why California has so many earthquakes? San Andreas is one of the most active fault zones in the world!! It is constantly moving!
