How Light Travels
Shadows and Mirrors
Lenses and light
The eye
100
The light energy we can see.
What is the visible spectrum?
100
This is a type of material that you can clearly see through like a window.
What is transparent?
100
This is how a shadow of a tree changes throughout the day.
What is long and thin, short and fat, long and thin?
100
A lens that is thicker in the middle than at the edges.
What is convex lens?
100
The outer part of the eye that protects the eye from dust.
What is the cornea?
200
The highest point on a wave.
What is the crest?
200
The is the type of material that you can see through, but it is difficult such as a plastic bin.
What is translucent?
200
This states that the angle of a wave as it hits a smooth object equals the angle of the wave when it bounces off an object.
What is the law of reflection?
200
This is a lens that is thinner in the middle than at the edges.
What is a concave lens?
200
These cells help your eye see very dim light.
What are the rod cells?
300
The lowest point on a wave.
What is the trough?
300
This is what makes a shadow form.
What is the sun hitting an opaque object?
300
This tells the brain about color.
What is the cone cell?
300
This is the way light travels.
What is in waves?
300
This is the colored part of the eye that controls the pupil.
What is the iris?
400
The difference between trough to trough or crest to crest.
What is wavelength?
400
This is the bouncing of a wave off an object like a mirror.
What is reflection?
400
This is a mirror where the surface is curved outward.
What is a convex mirror?
400
This controls how much light enters the eye.
What is the pupil?
500
When light is allowed to pass through an object.
What is transmit?
500
This is the bending of a wave around an object.
What is diffraction?
500
This is the type of mirror that has a flat surface.
What is a plane mirror?
500
This is the part of the eye that captures images.
What is the retina?
500
This is the color of an object that absorbs all the colors.
What is black?
