What is the iris?
This device records images using lenses.
What is a camera?

What is a plane mirror?
This measures how much a ray of light bends when it enters a certain material.
What is index of refraction?
These pieces of glass or plastic allow only a certain color of light to pass through.
What are filters?
This transmits the signals generated by the rods and cones to your brain.
What is the optic nerve?
The lens in this part of the telescope magnifies the image so you can see it clearly.
