So I am just beginning to emerge myself into quantum physics.
I am reading some things about the uncertainty principle and find myself very confused.
Why exactly is locating a particle in a small region of space make the velocity of that particle uncertain and vice versa?
I'm guessing it's because its really hard to measure the speed of a quantum particle when you slow it down enough to find it's position, and really hard to measure a position when a particle is moving. Is this right? So the more you know about its position, the less you know about its speed, and the more you know about its speed, the less you know about its position.
And why is the shorter the wavelength, the greater the certainty of a position, and the longer is less certain?
