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.

You wish to pick an element for a photocell that will operate via the photoelectric effect with visible light. Which of the following are suitable (work functions are in parentheses): tantalum (4.2 eV), tungsten (4.5 eV), aluminium (4.2 eV), barium (2.5 eV), lithium (2.3 eV) ?

X rays of wavelength 0.0100 nm are directed in the positive direction of an x axis onto a target containing loosely bound electrons. For Compton scattering from one of those electrons, at an angle of , what are

(a) the Compton shift,

(b) the corresponding change in photon energy,

(c) the kinetic energy of the recoiling electron, and

(d) the angle between the positive direction of the x axis and the electron鈥檚 direction of motion?

Calculate the de Broglie wavelength of (a) a 1.00keV electron, (b) a1.00keV photon, and (c) a1.00keVneutron.

A 100 W sodium lamp (位=589nm)radiates energy uniformly in all directions. (a) At what rate are photons emitted by the lamp? (b) At what distance from the lamp will a totally absorbing screen absorb photons at the rate of1.00photon/cm2.s? (c) What is the photon flux (photons per unit area per unit time) on a small screen 2.00 m from the lamp?

Monochromatic light (that is, light of a single wavelength) is to be absorbed by a sheet of photographic film and thus recorded on the film. Photon absorption will occur if the photon energy equals or exceeds 0.6eV, the smallest amount of energy needed to dissociate an AgBr molecule in the film. (a) What is the greatest wavelength of light that can be recorded by the film? (b) In what region of the electromagnetic spectrum is this wavelength located?
