Chapter 38: Q16P (page 1182)

Find the maximum kinetic energy of electrons ejected from a certain material if the material鈥檚 work function is 2.3 eV and the frequency of the incident radiation is 3.0脳1015Hz.

Short Answer

Expert verified

The maximum kinetic energy is 10.13 eV.

Step by step solution

01

Describe the equation of photoelectric emission:

The equation of photoelectric emission is given by,

hf=Kmax+桅 鈥�.. (1)

Here, h is the Planck鈥檚 constant, f is frequency, 桅is work function, and Kmax is the maximum kinetic energy.

02

Determine the maximum kinetic energy of electrons:

Hence, the maximum kinetic energy is 10.13 eV.

The existence of the atomic nucleus was discovered in 1911by Ernest Rutherford, who properly interpreted some experiments in which a beam of alpha particles was scattered from a metal foil of atoms such as gold. (a) If the alpha particles had a kinetic energy of 7.5MeV, what wads their de Broglie wavelength? (b) Explain whether the wave nature of the incident alpha particles should have been taken into account in interpreting these experiments. The mass of an alpha particle is4.00u (atomic mass units), and its distance of closest approach to the nuclear center in these experiments was about 30fm. (The wave nature of matter was not postulated until more than a decade after these crucial experiments were performed.)

X rays with a wavelength of 71 pm are directed onto a gold foil and eject tightly bound electrons from the gold atoms. The ejected electrons then move in circular paths of radius r in a region of the uniform magnetic field B鈫�. For the fastest of the ejected electrons, the product Br is equal to localid="1664288408568" 1.88脳10-4T路m. Find (a) the maximum kinetic energy of those electrons and (b) the work done in removing them from the gold atoms.

Question: (a) Write the wave function 蠄(x)displayed in Eq.38-27 in

the form 蠄(x)=a+ib, where aand bare real quantities. (Assume

that 蠄0is real.) (b) Write the time-dependent wave function 蠄(x,t)that corresponds to 蠄(x) written in this form.

The beam emerging from a 1.5 W argon laser (位=515nm ) has a diameter d of 3.0 mm. The beam is focused by a lens system with an effective focal length fLof 2.5 mm. The focused beam strikes a totally absorbing screen, where it forms a circular diffraction pattern whose central disk has a radius R given by 1.22fL位/dIt can be shown that 84% of the incident energy ends up within this central disk. At what rate are photons absorbed by the screen in the central disk of the diffraction pattern?

A metal plate is illuminated with light of a certain frequency. Which of the following determine whether or not electrons are ejected: (a) the intensity of the light, (b) how long the plate is exposed to the light, (c) the thermal conductivity of the plate, (d) the area of the plate, (e) the material of which the plate is made?
