Introduction
Halloween is almost here, and behind every corner there seems to lurk a spooky shadow! Luckily this is all they really are—just shadows that are part of decorations set up to give you a thrill while trick-or-treating. But where do these shadows come from, and how can some of them be so huge? Do this activity and find out how to generate the largest and scariest shadow of all!
Background
You need some kind of light source to generate a shadow. This can be the sun, a lamp or a flashlight. All light sources emit light waves that travel away from them. In optics, which is a special field of physics, this emitted light is modeled as a straight line called a light ray, which indicates the direction in which the light travels.
