Page 212 - An electromagnetic wave in space has both an electric and a magnetic field intensity which are at right angles to each other and to the direction of propagation of the wave. The two field intensities are related to each other by &
Page 161 - ... the quantities of polarized light in the reflected and refracted pencils are equal, whatever be the incidence. In the case of perpendicular incidence, these formulae are both reduced to the simple expression obtained by Young and Poisson; and when the incidence is 90°, or the ray grazes the surface, the intensity of the reflected light is equal to that of the incident, or the whole of the light is reflected, whatever be the reflecting medium. The latter conclusion has been verified by the observation...
Page 414 - ... between u and u + du, v and v + dv, and w and w + dw. In this discussion we mean, of course, by the expression the number " at any point " x,y, z the number in an infinitesimal element of volume dr=dxdydz which contains the point x, y, z.
Page 399 - Properties whose magnitude depends only on the initial and final states of the system, and not on the path of the change (how the change was accomplished), are known as state functions.
Page 305 - makes the angle \$ with the velocity of the observer referred to a system of co-ordinates which is at rest relatively to the source of light, the frequency v...
Page 575 - On the whole the evidence seems to be in favour of the elementary diatomic molecules containing oppositely charged as opposed to neutral atoms.
Page 12 - In the previous chapter we have stated that the force between two charged bodies of sufficiently minute size is proportional to the product of their charges divided by the square of the distance between them.
Page 232 - ... motion of the charged sphere has developed energy, and consequently the charged sphere must experience a resistance as it moves through the dielectric. But as the theory of the variation of the electric displacement does not take into account anything corresponding to resistance inconductors, there can be no dissipation of energy through the medium ; hence the resistance cannot be analogous to an ordinary frictional resistance, but must correspond to the resistance theoretically experienced by...
Page 434 - Effect. When an electric current flows across the lines of force of a magnetic field an electromotive force is observed which is at right angles to both the primary current and the magnetic field.
Page 547 - The difference in the refractive indices of the ordinary and extraordinary rays is proportional to the square of the applied electric intensity.
