What is Light?
100
This source of light come from heating an object up until it produces light.
What is an Incandescent source.
100
The change in speed of light as it enters a new medium produces this occurrence.
What is Refraction?
100
When you add more coloured light until you create white light

What is the Additive Theory

100

The white part of your eye provides structure and safety for the inside of the eye.

What is the sclera?
200

A type of mirror used on car rear view mirrors

What is a Convex mirror.

200
This source of light comes from the reaction between chemicals in a man-made device.
What is Chemiluminescence.
200

In a reflection and refraction diagram, what is the light source going towards the normal called?

What is the incident ray

200

Optical elements used to magnify or focus images

What are lenses

200

The first thing that light passes through when entering the eye. 

What is the cornea?

300

Light travels in a straight line. This is also called...

What is Rectilinear Propagation?

300
This source of light comes from chemical reactions that occur within a living organism.
What is Bioluminescence.
300
The Law of Reflection states that these two things are equal.
What are the Angle of Reflection and the Angle of Incidence.
300

In this type of mirror, images appear larger and flipped.

What is a concave mirror

300

This part of the eye controls how much light is let in.

What is the pupil?

400

If light rays hit a rough surface, and all the rays reflect at different angles, it is called...

What is diffuse reflection

400
This source of light comes from the use of electricity transferring through mercury vapour. The mercury vapour releases ultraviolet light which is absorbed by a phosphor coating which then releases visible light.
What is Fluorescence.
400
When light enters a more dense medium it will bend towards or away from the normal line?

Rods and cones are special cells called...

What are photreceptors?

500

This scientist realized that light bounces off objects and travels to our eyes.

Who is Iban Al Haytham?

500
This source of light occurs when particles are able to absorb the energy from a light source and release it at a later time.
What is Phosphorescence.
500
The imaginary line that extends up 90 degrees from the surface of an object.
What is the Normal Line?
500

When all waves of white light become separated to create a rainbow

What is dispersion?
500

The first line of defense from airborne dirt, dust and debris.
