What is a wave?
What is a rhythmic disturbance that carries energy
100
The distance from crest to crest or trough to trough?
What is wavelength
100
The bending of light waves around a barrier?
What is diffraction
100
What is a sound wave?
Produced by the vibration of particles in a medium and moves slowly through the medium.

Two parts of retina help you see:
Rods: work at low levels of light; used mainly at night.
Cones: work at bright light levels; allow us to see color.
200
Waves that use matter to transfer energy?
What is mechanical waves
200
This color has the longest wavelength and the lowest frequency?
What is red.

The model shows a light wave in a fish tank. The solid arrow represents the wave moving through salt water, which has a density of 1.03 g/cm^3. The glass of the tank has a density of 2.6 g/cm^3. Which dashed arrow represents the path the light wave will travel after reaching the glass?
B
200
The small part of the electromagnetic spectrum we can see.
Colors exist at different wavelengths from lowest energy to highest energy
ROYGBIV
What is Visible light
200
Thicker in the middle than it is at the edges.
Directs light so it converges, or comes together at a point called the focus
Convex Lens
300
A wave who's energy causes the matter in the medium to move up and down at right angles?
What is transverse waves
300
Why do you see lightning before you hear thunder?
What is light travels faster than sound
300
Which behavior of light allows magnifying glasses and contact lenses to bend light?
What is refraction
300
What type of wave is a sound wave?
What is a longitudinal (compressional) wave
300
Thinner in the middle than it is at the edges.
Causes light to diverge, or spread out
Concave Lens
400
What are electromagnetic waves?
What is a wave that does not require a medium to transfer energy
400
Name 5 tpes of electromagnetic waves.
What is Radio waves, Infared waves, microwaves, Xrays, Gamma rays, ultraviolet waves, visible light waves
400
State the definition for reflection, refraction, diffraction, and absorption. (Key words)
What is bounce back, bends when it goes from one medium t another, bends around a barrier, disappear
400
The creation of a sound starts when something is caused to
What is vibrate
400
What is lens?
a transparent object with at least one curved surface.
500
Name an electromagnetic wave with low energy and then name an electromagnetic wave with high energy?
What is a radio wave has low energy and a gamma rays have high energy
500
What is the amplitude measured from? What does the amplitutde tell us about a sound?
What is crest to rest position or trough to rest position. Amplitude tells us how loud a sound is.
