Page 1 - ... v," and which is the ratio of the electromagnetic unit of electric charge to the electrostatic unit. The measurement of the same electrical quantity on the two systems of units will enable us to find
Page 29 - In the preceding section we saw that light polarized perpendicularly to the plane of incidence is not reflected at all when a becomes equal to the polarization angle a0 = arc tan n.
Page 26 - The electromagnetic theory of light has thus united in itself, as far at least as reflection and refraction are concerned...
Page 2 - Maxwell has arrived at the capital conclusion that " the velocity of propagation in air [or in vacuo] is numerically equal to the number of electrostatic units contained in an electromagnetic unit of electric charge ". The dimensions of this " number " c, or ratio of units, are obviously those of a velocity.
