Find the probability density of a particle moving in an interval of 101o the box. the length of the one-dimensional box is 20x10-10 m (a) 0.2 (b) 0.3 (c) 0.4 (d) none of the above

The probability density function is

Solution:

Position of the particle in the box, S =

Length of the box, L =

Now, the probablity is given by:

P =

Now,

The probability density,

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid
