Two
This can sometimes fool your brain can into seeing colors or movements that aren't really there.
Optical illusions
The scale on which light is measured is called this.
The electromagnetic spectrum
This bending of light creates rainbows.
Refraction
This part of your eye contains cones and rods.
Retina
Bees can see this type of light that humans cannot.

One measures how long a light wave is, the other measures how often the wave repeats.

Humans have this many different cone cells.
Three
Birds can see in Ultraviolet (UV) light to help them do this.
Find food / choose mates
This is the reason why the sky is red and orange during a sunrise/sunset.

This is the percentage of the entire electromagnetic spectrum of which visible light occupies.
0.0035%
This is why red is always on the outside or top of a rainbow.
Red light bends/refracts less than other colors
Light must first pass through the ____ in the eye.
Cornea
Owls can see so well at night, not only because they have such large eyes, but also because of this function in their eyes.
They have a lot of Rod cells
If an object reflects every color of visible light except blue, this color will appear.
Yellow
Objects look like the colors they reflect, not absorb. Reflecting green and red but not blue makes the object look Yellow.
