@physicsbyabbas: In quantum mechanics, the wave function—usually written as ψ(x,t)—is not a physical wave like water or sound. It’s a probability amplitude. That phrase sounds bureaucratic, but it hides something deep: the wave function contains all the information you can possibly know about a quantum system. Here’s the key idea. The wave function itself is generally complex (it can involve √−1), so it’s not directly observable. What is observable is its magnitude squared: |ψ(x,t)|² This gives the probability density of finding the particle at position x at time t. Not where the particle is, but where it is likely to be found if you measure it. #physics #viral #fyp #physicsbyabbas #quantummechanics @astrosciencee
