100

The bending of light when it travels from one medium to another. 

Whta is refraction?

100

This type of lens diverges light rays.

200

The angle of incidence equals the angle of reflection

What is the Law of Reflection?

200

Light bends TOWARD the normal line.

What happens when light moves from one medium to a denser one?

200

This type of lens converges light rays to form an image.

What is a double convex lens?

300

The part that maintains the shape of the eye and provides support

What is the vitreous humour?

300

Light that comes from heat

What is incandescent? 

300

The imaginary line perpendicular to the surface at the point of incidence

What is the normal line?

300

Light bends AWAY from the normal line. 

What happens when light moves from one medium to a less dense one?

300

An optical device that uses a convex lens to gather and focus light. 

What is a refracting telescope?

400

The part of the eye that adjusts the shape of the lens for focusing

What is the ciliary muscles?

400

Give an example of a non-luminous object.

Answers vary.... Could include (but not limited to) a rock, a desk, or the moon. 

400

The angle between the reflected ray and the normal line.

What is the angle of reflection?

400

An object that prevents light from passing through it is called this.

What is opaque?

400

An optical device that uses a concave mirror to gather and focus light. 

What is a reflecting telescope?

500

The part of the eye that transmits visual information from the eye to the brain, allowing us to see

What is the optic nerve?

500

Light that comes from things that are man-made vs light that comes from a natural source.

What is artificial vs natural light sources?

500

Draw a Ray Diagram. 

Check drawing. 

500

A mirror that makes images appear to be "zoomed out"

What is a convex mirror? 

500

The part of the eye that can cause near-sightedness or far-sightedness.


BONUS: How can you fix this?

What is the lens?


BONUS: Add a double convex lens for farsightedness and a double concave lens for nearsightedness.
