100

This type of material, which works like a window, allows light to pass through easily.

What is transparent?

100
This device allows you to see great detail, such as micro-organisms, by combining the power of at least two lenses.
What is a microscope?
100
A mirror with a surface curved outward, like the bottom of a bowl.
What is convex?
100
This is the bending of light when it travels from one medium to another. An example is a fish in water looking like a different spot than it actually is.
What is a refraction?
100
This is the area of the eye that sends information to the brain.
What is the optic nerve?
200

Like a brick wall, this type of material does not allow any light to travel through them.

What is opaque?

200

This device, often used by treasure hunters, uses two refracting telescopes to allow the user to see further

What are binoculars?

200
A lens that is thinner in the centre than on the edges and curves inward.
What is concave?
200
A line perpendicular to the mirror at the point of reflection is called this.
What is normal?
200
This part of the eye has muscles to control the entering of light through the pupil.
What is the iris?
300

A sheet of paper with a flashlight shining on it would be an example of this type of material.

What is translucent?

300
This is the term for any technology that uses light.
What is an optical device?
300
In a convex lens, when light passes through, the rays do this.
What is converges (comes together)?
300
This is when light hits a bumpy or uneven surface.
What is diffuse reflection?
300
The lens of the human eye is a convex lens. That means that when it takes in light from an object, it refracts the light rays, by focusing them on the retina. If the eye is too short, the image will form behind the retina. This condition is _______.
What is farsightedness?
400

Like a lamp, an object that is a source of light could be called a ________ object.

What is luminous?

400
A type of telescope that uses a large circular mirror that curves inward (concave mirror).
What is a reflecting telescope?
400
In a concave lens, the light passing through does this.
What is diverges (spreads out)?
400
The angle between the incident ray and the normal is called this.
What is the angle of incidence?
400

This type of vision allows a person to see objects that are nearby, but NOT as well far away. 

What is near-sighted?

500

This is an illustration that demonstrates how light travels.

What is a ray diagram?

500

This specific device controls the amount of light that enters a camera

What is a diaphragm?

500
In a convex lens, if an object is placed closer than the focal point, the image will be on this side of the lens.
What is the same side?
500
During refraction, when light travels through a new medium that is more dense, it will refract this way (towards or away from the normal).
What is towards normal?
500
Achromatopsia causes people to be completely colour-blind, which are most likely having non-functional this.
What is cone cells (all)?
