Prove that Light is a Wave! - 3 In-class Experiments

-

 Here are some 3 cool experiments that you can do in class if you have a laser pointer. One of them shows that light is not just a stream of particles/ photons, but a wave at the same time.

1. Laser does not spread out with distance the way the flashlight beam does
2. You cannot see a laser beam from a side. You need a mist to disperse it
3. The famous "double slit experiment"  

There is only one hard word that we have to learn today - Diffraction.
