Not illustrated. 1916 Excerpt: ...For the present problem we are concerned only with the x and z displacements, i.e. with the motion projected into the plane of Fig. 17. Integrating equation (14) and the first of equations (13) subject to the initial conditions above, and eliminating t, we get-Ha, +(, i5&0 (, s) where a, is the perpendicular distance between the planes, and xx is the vertical level at which an electron emitted at the level x0 with velocity components -0 w0 strikes the opposite plane. Considering electrons setting out with different values of -0, those for which u0 exceeds the right-hand side of (15) will strike the plane at a level higher than xu and those with smaller values of u0 at a lower level than xv It follows from this that if f is the width of the hot strip and that of the slit, both supposed to be of indefinite length, the current passing through the slit at the level xx is where N, is the total number of electrons emitted by the strip, and F(w0)dw0 and / (u0)du0 are the proportions of them for which w0 lies between w0 and Zf0 + dw0, and -0 between -0 and -0 + du0 respectively. If f.and f are both small, as in the experiments, there are two important cases for which (16) reduces to a quite simple expression. First suppose that VieA w-03 is a large quantity. It is worth while remarking that if, as we have seen is the case, Maxwell's Law holds for w0, this condition cannot be satisfied by all the electrons; since all values of w0 up to infinity are included in the theoretical formula. On the other hand if V1 is of the order of i00 volts the fraction of the whole number of electrons which does not satisfy this condition is exceedingly small and may safely be neglected. When 2N/mw is large, (16) reduces to after substituting ..

Seller's Description:
GOOD. Ex lib. markers on spine and inside. Spine has minor wear marks and, regretably, there is what looks like mud splattering on the title page but inside it is a nice clean copy. This is a rare original copy of Richardson's book on thermionic emission; the second, revised and improved edition. Owen W Richardson was major figure in British science in the first half of the 20th century, winner of the Nobel Prize for Physics in 1928 for his work on thermionic emission, the phenomena at the heart of electronic valves, TV, radar and cathode-ray tubes in general.
