Waves Basics
This is the starting point of a wave where there is no movement.
What is the rest position?
The highest point of a transverse wave.
What is a crest?
This wave moves particles up and down, perpendicular to energy flow.
What is a transverse wave?
When light bounces off a surface.
What is reflection?
What is opaque?
This is how often a wave passes a point in a given time.
What is frequency
The lowest point of a transverse wave.
What is a trough?
This wave moves particles back and forth, parallel to energy flow.
What is a longitudinal wave?
When light bends as it passes through different materials.
What is refraction?
This material allows some light through, but not clearly.
What is translucent?
This is the substance or material through which a wave travels.
What is a medium (matter)?
The height of a wave from rest position to crest or trough.
What is amplitude?
Sound waves are an example of this type of wave.
What is a longitudinal wave?
When a wave spreads out after passing through an opening.
What is diffraction?
This material allows light to pass through clearly.
What is transparent?
This type of wave can travel through empty space.
What is an electromagnetic wave?
In longitudinal waves, this is where particles are spread apart.
What is rarefaction?
Light waves are an example of this type of wave.
What are electromagnetic waves?
When light energy is taken in by a material.
What is absorption?
These are the shortest wavelength, highest energy waves.
What are gamma rays?
This type of wave requires a medium to travel.
What is a mechanical wave?
In longitudinal waves, this is where particles are close together.
What is compression?
This determines how high or low a sound is.
What is pitch?
When light passes through a material.
What is transmission?
These are the longest wavelength, lowest energy waves.
What are radio waves?
