When waves travel, they oscillate up and down. voice-verified

But when two waves try to oscillate the same point in space at the same time, you get something known as interference. voice-verified

Imagine you had a bathtub with a rubber duck sitting on the surface. voice-verified

Two waves reach the duck at once. voice-verified

One wave tries to raise the duck up at the exact same time the other wave tries to drop it down. voice-verified

What happens? voice-verified

Provided the waves are of the same magnitude and are perfectly out of phase, voice-verified

they will cancel each other out and the duck would not move at all. voice-verified

This is called destructive interference. voice-verified

Similarly, if the waves both tried to raise the duck up at the same time, the duck would be raised twice as high. voice-verified

This is known as constructive interference. voice-verified

Because waves tend to expand in a circle, two waves next to each other will start to both constructively and destructively interfere with each other. voice-verified

Here are two waves in water. voice-verified

See these lines? voice-verified

These calmer patches are where the waves are cancelling each other out. voice-verified

This is the effect we see with light travelling through the two slits. voice-verified

As the light from one slit propagates, it cancels out the other wave of light at certain points, creating the interference pattern that Young noticed on the board. voice-verified

So, the mystery was solved. voice-verified

Light was a wave and not a particle. voice-verified

Except, there is more to this experiment than meets the eye. voice-verified
