ROY G BIV; red, orange, yellow, green, blue, indigo, violet
100
Define Reflect, Refract, and Absorb.
Reflect - Light bounces off a surface
Refract - Light bends as it changes speed in different substances.
Absorb - Light waves are trapped in a surface.

What is the path sound takes?
The Pinna travels sound waves into the Auditory Canal which travels sound waves into the eardrum. The ear drum travels vibrations into the hammer which travels vibrations into the anvil stirrup. which travels vibrations into the cochlea. Finally the cochlea travels sound waves into the auditory nerve which travels nerve impulses into the brain: auditory cortex.

What is the path the light takes throughout the eye
Why is the fire box red? Why is the that sock blue?
The fire box is red because it absorbs all the colors except red because red bounces off. The sock is blue because it absorbs all the colors but blue because blue bounces off.

Define Interneuron
A neuron that carries nerve impulses from one neuron to another.

Define synapse
The gap between two neurons. (nerve cells)
300
Define Pinna, Auditory Canal, and hammer
Pinna - Directs sound waves into the auditory canal. Protects its opening.
Auditory Canal - produces earwax that keeps harmful dust and particles out of the inner canal.
Hammer - Passes vibration down to the anvil
400
Which type of lens makes an object appear larger? Describe its shape.
Convex lens because the glass is thicker in the center than at the edges
400
Define wave frequency
The time it takes for a wave to go from another wave per second
400
What is sound?
Tiny vibrations and sound waves
