Chapter 6: Q47E (page 1316)

A scientist has devised a new method of isolating individual particles. He claims that this method enables him to detect simultaneously the position of a particle along an axis with a standard deviation of 0.12 nm and its momentum component along this axis with a standard deviation of.Use the Heisenberg uncertainty principle to evaluate the validity of this claim.

Short Answer

Expert verified

, this claim is invalid.

Step by step solution

01

Heisenberg’s uncertainty principle

According to Heisenberg's uncertainty principle, it is impossible to precisely measure or calculate an object's position and momentum.

02

Evaluating the validity of the claim

The uncertainty in detection is represented by the standard deviation. As a result, the uncertainty in the particle's position is, and the uncertainty in its momentum is along the same axis.

As a result, the product of these two quantities is;

Using the Heisenberg鈥檚 uncertainty principle is;

Hence,, this claim is invalid.

When ultraviolet light with a wavelength of falls on a clean copper surface, the stopping potential necessary to stop emission of photoelectrons is 0.181V. (a) What is the photoelectric threshold wavelength for this copper surface? (b) What is the work function for this surface, and how does your calculated value compare with that given in Table ?

In an experiment involving the photoelectric effect, if the intensity of the incident light (having frequency higher than the threshold frequency) is reduced by a factor of 10 without changing anything else, which (if any) of the following statements about this process will be true? (a) The number of photoelectrons will most likely be reduced by a factor of 10. (b) The maximum kinetic energy of the ejected photoelectrons will most likely be reduced by a factor of 10. (c) The maximum speed of the ejected photoelectrons will most likely be reduced by a factor of 10. (d) The maximum speed of the ejected photoelectrons will most likely be reduced by a factor of 110. (e) The time for the first photoelectron to be ejected will be increased by a factor of 10.
