Wave Diagram
The height of a wave
What is amplitude?
What is the speed of a wave when the wavelength is 5 cm and the frequency is 3 waves per second?
15 cm per second
A wave that travels through a medium?
The medium of an ocean wave.
What is water?
The medium of a sound wave (usually).
What is air?
The lowest point of a wave
What is trough?
The Greek letter used to represent wavelength.
What is lambda λ?
What is one example of a mechanical wave that we talked about in class?
The source of energy for a regular ocean wave.
What is wind?
Does a sound wave travel as a transverse wave or a compression wave?
compression wave
The highest point of a wave
What is crest?
What is the relationship between frequency and wavelength?
They are inversely related?
What is the medium of a spring wave?
The spring
There are two things that happen when a wave moves closer to shore.
Does the frequency of a sound wave correspond to the volume or pitch?
What is pitch?
The point where a wave crosses the resting line
What is node?
What happens to frequency when wavelength increases?
It decreases?
What happens to the particles in a wave when energy transfers?
They stay in place
The source of energy for a tsunami wave.
What is underwater volcanoes and earthquakes?
Does the amplitude of a sound wave correspond to the pitch or volume of a sound wave?
What is volume?
How do you measure wavelength?
Crest to crest, trough to trough, or 3 nodes
What happens to frequency when wavelength decreases?
It increases?
What are two characteristics that all waves share?
They move back and forth and transfer energy
Why are tsunamis hard to detect?
Because they travel on the ocean floor.
Can a sound wave (mechanical wave) travel in a vacuum (empty space)? Why or why not?
No, because there are no air particles to act as the medium.
