Waves create interference pattern on the wall after passing the double slit.

Particles create two line clusters on the wall after passing the double slit.

​

Tiny particles such as electrons create interference pattern on the wall after passing the double slit. Are they waves? Or are they particles? Which slit did each individual electron go through? Left or right?

​

Eureka!!!

It turns out that if one attempts to observe an electron in either slit, the electron will again create a two-line particle pattern and behave like particles. However, if one looks through neither slit, the electron will again create a interference pattern and behave like waves.

See how the music and animation changes when you step in and out of the slits!
