What is Youngs Double Slit Experiment?
Imagine a dark room with a screen at one end, and in the center of that screen, there’s a small opening, or slit. Behind this screen, there’s a source of light, emitting waves that pass through this single slit, creating a pattern of light on the screen. So far, so good, right? But here’s where it gets interesting.
Now, instead of one slit, we introduce another slit right next to the first one. This means there are now two openings for light to pass through.
What do you think will happen?
Well, classical physics might lead us to believe that we’d simply see two bright spots of light on the screen, aligned with the slits. But that’s not what happens.
When both slits are open, something peculiar occurs. Instead of just two bright spots, we observe a pattern of alternating bright and dark bands on the screen. This pattern is known as an interference pattern, and it’s a key feature of wave behavior.
