How does the light from a laser differ from a flashlight? Learn how lasers make light, and what makes that light unique. Supplies needed to participate in all the activities: ● Inexpensive red laser pointer ● Flashlight (single bulb works best, but multiple LEDs can work too ● A ruler ● An old recordable CD that you can destroy. If you happen to have a diffraction grating slide, even better! ● A piece of waxed paper or other translucent paper that you can shine light through
