Another familiar illustration of refraction is the appearance of a stick—an oar, for ex-ample—when held obliquelyin the water (Fig. 864). Apencil of light coming fromany point on the stick, uponemergence from the water,is refracted downwards andenters the eye as though itcame from a point nearer the surface of the water. Thus thepart of the stick immersed in the water appears lifted up. 367. Explanation of Refraction by Means of Waves. First, lei us consider what might naturally happen wlien a regiment of soldiers passes from smooth ground to rough ploughed land. It is evident that the rate of marching over the rouo-h lan
