How many lenses does the light pass through between the light source and your eye?
how does light effect your eye? In a compound light microscope? The light passes through three lenses between the light source and your eye. The first lens is the condenser lens.. The second lens is the objective lens. The third and final lens is the Eyepiece, also known as, the ocular lens. This is the lens you look through. These are the lenses that light must pass through to get from the light source to your eye.
How do you tell if sunglasses are polarized?
If they're on a rack with others, take two pair and hold them the same like you're looking through both, and then look through both lenses at once. Then rotate one pair of glasses through 90 degrees. You should have gone from seeing through both darkened lenses to not being able to see anything at all through them. Assuming they're all by themselves - found in the bottom drawer, or on a park bench - hold them up and look at the blue sky through them. Rotate the lenses. The sky should brighten and darken through polarized lenses. Bees use the polarization of sunlight to help them navigate. Alternately look at a digital display on a watch or other equipment through the lens (Not LED display). Rotate the lens the display will go black at part of the rotation (The display has a sheet of polarized material - reducing this solution to the first answer)
