Light rays travel in...
What is straight lines.
100
True or false, the higher the amplitude, the louder the sound.

True.

200
The light ray that first hits the mirror
What is the incident ray

When light enters a new medium this change causes the light to bend.
What is the speed of the light slows down
200

Allows light to enter

 pupil 

200

What is the name of the spectrum light is a part of?

The electromagnetic spectrum

200
True or False: The image that is projected onto your retina is right-side up
What is false
300
If the angle of incidence is 54 degrees, the angle of reflection will be...
What is 54 degrees.
300

In what direction does light refract in a convex lens?

Inwards

300

Adjusts how much light enters the eye

 iris and pupil

300

What is the name of the part of the electromagnetic spectrum that contains all the light we can see?

Visible light

300

This kind of object completely absorbs all light 


Opqaue 
400
In order for an image to appear on a surface, the surface must be what?
What is smooth/reflective.
400
The ray of light which leaves a medium.
What is the emergent ray.
400

The very back of the eye that contains cells and captures the image

 retina 

400
Material that does not let any light pass through it
What is opaque material.
400

Desribe compression and rarefaction in a longitudinal wave.

Compression: region where particles are close together.

Rarefaction: where particles are far apart from each other.

500
The Law of Reflection states that these two things are equal.
What is the Angle of Incidence and the Angle of Reflection.
500
When light enters a denser medium, will it bend toward or away from the normal line?
What is toward the normal line.
500

What is the optic nerve, and where is it located.

Sends information received by the eye to the brain. It is located at the back of the eye.

500
The individual units that make up compound eyes.
What are ommatidia.
500
Describe what happens to the pupils as you enter a brightly lit room. 

The pupils will constrict (get smaller) to prevent too much light from entering the eye.
