Lasers and Flashlights
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
