Chapter 39: Q4. (page 1136)

FIGURE Q39.4 shows the dot pattern of electrons landing on a screen. a. At what value or values of x is the electron probability density at maximum? Explain. b. Can you tell at what value or values of x the electron wave function c1x2 is most positive? If so, where? If not, why not?

Short Answer

Expert verified

a: x = -2, +2

b: x = -2, +2

Step by step solution

01

Concept used:

Wave function of electron gives the value of its probability density in a certain region.

02

Part a:

At x = -2, +2

Because as it can be seen in the given image, most number of electrons hit the screen at these locations so these are the regions where electron probability density will be maximum.

03

Part b:

The wave function will also be most positive at x = -2, +2 because wave function tells about distribution of probability density of electron.

Soot particles, from incomplete combustion in diesel engines, are typically 15nmin diameter and have a density of 1200kg/m3. FIGURE P39.45 shows soot particles released from rest, in vacuum, just above a thin plate with a 0.50-渭m-diameter holeroughly the wavelength of visible light. After passing through the hole, the particles fall distance d and land on a detector. If soot particles were purely classical, they would fall straight down and, ideally, all land in a 0.50-渭m-diameter circle. Allowing for some experimental imperfections, any quantum effects would be noticeable if the circle diameter were 2000nm. How far would the particles have to fall to fill a circle of this diameter?
