Things to remember:
Magnification happens when light travels through a curved surface
White paper reflects light
Black paper absorbs light
Lenses bend light
Infrared is closely related to heat
Speed of light is 156,000 miles/second
Concave lenses makes objects bigger
Convex lenses makes objects smaller
When focus point of light is before the retina, you are nearsided, when focus point of light is passed the retina, then you are farsided, but when the focus of light hits the retina right on point, then you have normal vision.
Light is made up of small particles call photons.
The retina is made up of photoreceptors called rods and cones.
We have about 120 million rods in our retina and they help us to detect light
We have about 6-7 million cones in our retina and they help us to detect different wavelengths of color.
