Waves are caused by repeated disturbances called these.
What is a vibration?
Point A on a longitudinal wave is this.
The bouncing back of a wave as it meets a surface or boundary is called this.
What is a reflection?
Humans can see this part of the EM spectrum.
What is visible light?
This part of the eye transfers nerve impulses to the brain. (identify letter and name)
What is E, the optic nerve?
The material through which both mechanical and electromagnetic waves can travel is called this.
What is a medium?
This is the amplitude of this wave
What is C?
This bending of a wave occurs when a wave changes speed as it goes from one medium to another.
What is refraction?
These types of waves are low energy, long wavelength, and low frequency.
What are radio waves?
This is the area of the eye with light sensitive cells that receives the light.
What is the retina?
This is a
What is a transverse wave?
The number of waves that pass a given point in a certain amount of time is known as this.
What is the frequency?
This occurs when energy is not transferred through or reflected by a medium.
What is absorption?
These types of waves are high energy, short wavelength, and high frequency?
What are gamma rays?
This describes the shape and opacity of the lens (c) of our eye.
What is convex and transparent?
This is a (must say both names)
What is a compressional or longitudinal wave?
This happens to energy as amplitude is increased.
What is an increase in energy?
This is called this sort of interference.

What is constructive interference?
This is a list of the visible light spectrum from lowest energy to highest energy.
What is ROY G BIV (Red, Orange, Yellow, Green, Blue, Indigo, Violet)
When no part of the visible light spectrum is absorbed, the object will appear like this.
What is white?
Sound is an example of this type of wave and moves like this form of wave. (2 vocabulary word answer)
What is a mechanical and longitudinal (compressional) wave?
This happens to frequency when a wavelength is shortened.
What is an increase in frequency?
If a crest and a trough meet on two transverse waves, this sort of interference will occur.
What is destructive interference?
Thermal imaging and TV remotes use this frequency of the EM spectrum.
What is Infrared radiation?
These are two wave behaviors that allow us to see color.
