Light Guidance Science Project Idea
How light effects may guide us in the selection of clothing.It is not only by the use of lenses that our sense of sight may be deceived.Have you ever noticed that one's feet look larger when white shoes are worn, that stout people look stouter when dressed in white, and that a house once white, which has been painted a dark color, appears to have become smaller in size?
The three systems of lines are equally distant from one another at all points.Do they appear so? Certain arrangements of lines also deceive us.A stout person appears stouter when he wears clothes which have horizontal stripes, and a thin person appears thinner when he wears clothes which have vertical stripes.The way in which lines deceive us is illustrated by the preceding figure.Endeavor to explain the following: 1. Why ground glass or glass with an irregular surface is used in office partitions. 2. Why concave mirrors are used behind headlights of locomotives, trolley cars, etc. 3. Why undimmed automobile headlights are not usually permitted. 4. Why corrugated glass is used in automobile head lights. 5. Why a piece of glass will cast a shadow. 6. The presence of a wavy appearance over a hot radiator or stove, or over a dry road on a hot day. 7. Why colored glasses are frequently worn at the seashore and by motorists. 8. Why it is more difficult to see objects when you first go out at night than later. 9. Why it is difficult to see when you enter a brilliantly lighted room after having been in the dark. 10. Why the inside of a camera is painted black. 11. Why a cake of ice is transparent, and a block of snow is not.
