Question

In studying quantum mechanics, we find that all waves have object-like qualities and all objects have wave-like qualities. That technically means that all objects must obey the Heisenberg Uncertainy Principle. Let's assume the object is a 64 kg physics student and she moves through a 0.71 m wide door. We know that as she moves through the door, she must be somewhere inside its frame.

1) What is the uncertainty in her velocity?

?vstudnet =_______m/sec

2. Lets assume she "enters" the room by moving 1 meter from the outside of the door to inside. At this speed, how long would it take for the student to enter to room?

tenter =__________ years

Explanation / Answer

To define the uncertainity it is necessary to know the wavelength of the particle

for a bigger particle it is highly impossible to define wavelength

since it is difficult to define wave length for a molecule even
