at right angles to the reflected ray. From this it follows that the angle of refraction is thecomplement of the angle of incidence, or calling the latter,the angle of polarization, a, (1) tan a = n. For glass this angle has a value of 57° or 58°. Polarization,even at the polarizing angle, is not… … Fig. 471. parallel to the first, the light will all be reflected and nonerefracted; but if the second glass be revolved about thedirection of the incident light as an axis, through a rightangle (Fig. 471 b), no light will be reflected, all the wavesbeing refracted. The first mirror in this…
