300
How fast a wave travels is known as
Wave speed or velocity.
300
What do you call a wave that travels along the surface of a medium?
A surface wave.
300
when waves bounce back from a surface they cannot pass through it is called _____________________.
Reflection
300
What is the frequency of the waves in this picture?
3 Hertz
300
The distance between two crests or two troughs.
Wavelength
400
Which type of wave moves the particles parallel to the direction of the wave.
Longitudinal
400
Transverse waves move __________________to the direction of energy transferred.
Perpendicular
400
What would the amplitude of a wave be if it measures 8cm from the top of the crest to the bottom of the trough?
4 cm because you would divide in half
400
The distance from rest(equilibrium) to trough.
Amplitude
400
The low point of a wave
Trough
500
The matter that waves travel through is known as
Medium
500
In this type of wave the medium and the energy moves in the same direction.
Longitudinal Wave
500
What type of wave does not need a medium to travel to?
Electromagnetic waves.
500
This happens when sound waves bounce back from a surface that they can’t pass through.
Echo
500
Measures the height of the wave.
Amplitude
600
Which type of wave moves particles in right angles in the direction of the waves?
Transverse
600
What is a medium? Give the 3 examples
Material through which waves can travel though. (Gas, liquids, solids)
600
What are the two types of mechanical waves called?
What is transverse and longitudinal waves.
600
Frequency of a wave is measured in?

600
The high point of a wave
crest
What does the Latin root word "trans" mean? (50 points)
700
A disturbance that carries energy is called
a wave!
700
What does the wavelength measure?
How long one wave is.
700
Give me 3 examples of a mechanical wave.
transverse wave, longitudinal waves, surface waves
700
This is when waves bend as they enter a new medium at an angle.
Refraction
700
The number of wavelengths that pass a given point per second
Frequency
