Eyeball
This part of the eye senses light and colour
What is the retina
What TYPE of light is emitted from an object (like a candle) that gets so hot that it glows?
What is an incandescent light source.
The angle of THIS always equals the angle of incidence
What is reflection
Provide an example of a device that uses a convex mirror
Car side mirrors, security mirrors.
The type of mirror that makes light converge
What is concave mirrors
How does the iris reflex respond when you enter a dark room?
The iris shrinks, the pupil dilates.
This changes the size of the pupil to let in light
What is the iris
This is the type of light emitted from a glow stick
What is chemiluminescent
This is when light moves from one medium to another and bends
What is refraction
Provide an example of a device that uses a concave mirror
Reflecting Telescopes, makeup mirrors
The type of mirror that makes light diverge
What is a convex mirror
The technical name for people who can see far away, but not up close.
What is HYPEROPIA (farsightedness).
This is the opening of eye that lets in light
What is the pupil
This is the emission of light from a living organism.

What is a concave lens.
Inverted
What part of the camera acts like the pupil of the eye.
What are the aperture
This is the type of light source found in glow-in-the-dark objects
What is phosphorescence.
State the law of reflection
The angle of reflection equals the angle of incidence
Objects appear smaller and farther away with this type of mirror
What is convex
Rays converge with this type of lens.
What is a convex lens.
This is the technical name for people who can see close up but not faraway.
What is MYOPIA (nearsightedness).
Where is the Retina located?
It is found on the back of the eye.

If light bends away from the normal line it has entered a medium that is ______ dense
This type of mirror used in makeup mirrors
What is a concave mirror.
This type of lens is used to fix farsightedness.
What is a single sided convex lens.
How does the eye accommodate to focus on a distant object?
The lens gets thinner/lengthened
What is the Tapetum Lucidum?
What is the reflective layer in some animal eyes that allows them to see at night/twilight?
