- Suppose the fractional efficiency of a cesium surface (with work function 1.80 eV) is 1.0 * 10-16; that is, on average one electron is ejected for every 1016 photons that reach the surface.What would be the current of electrons ejected from such a surface if it were illuminated with 600 nm light from a 2.00 mW laser and all the ejected electrons took part in the charge flow?arrow_forwardIn Millikan’s oil-drop experiment, one looks at a small oildrop held motionless between two plates. Take the voltagebetween the plates to be 2033 V, and the plate separation tobe 2.00 cm. The oil drop (of density 0.81 g/cm3 ) has adiameter of 4.0×10−6 m . Find the charge on the drop, interms of electron units.arrow_forwardWhat is the maximum kinetic energy of electrons knocked out of a thin copper foil by Compton scattering of an incident beam of 17.5 keV x rays? Assume the work function is negligible.arrow_forward
- In the Millikan oil drop experiment tiny charged oil droplets generated by a spray are allowed to fall under gravity through a hole in a top electrode, T, towards a bottom electrode B separated from T by 1 cm. When a holding voltage Vh = +0.25V is applied between T and B the droplets are seen to be suspended motionless between the electrodes. What is the specific charge of the droplet q/m?arrow_forwardThe binding energies of K-shell and L-shell electrons in copper are 8.979 and 0.951 keV, respectively. If a Ka x ray from copper is incident on a sodium chloride crystal and gives a first-order Bragg reflection at an angle of 74.1° measured relative to parallel planes of sodium atoms, what is the spacing between these parallel planes?arrow_forwardThe current of a beam of electrons, each with a speed of 1.200*10^3 m/s, is 9.000 mA. At one point along its path, the beam encounters a potential barrier of height -4.719 mV and thickness 200.0 nm.What is the transmitted current?arrow_forward

Both have identical dimensions of length L (1 mm), width W (1 mm), and depth (thickness) D (0.1 mm). One sample, labeled A, has an electron lifetime of 1 μs whereas the other, labeled B, has an electron lifetime of 5 μs. a. At time t = 0, a laser light of wavelength 750 nm is switched on to illuminate the surface (L × W) of both the samples. The incident laser light intensity on both samples is 10 mW cm−2.
