...other similar phenomena. He ought to be able to explain why the image in a plane mirror must appear as far behind the mirror as the object is in front of it ; why a stick appears bent when dipped obliquely into water ; and why the bottom of a river or lake,... | |

...A plane mirror simply alters the direction of the rays, and makes them appear to come from a point as far behind the mirror as the object is in front of it. Now, as we -always see an object in the direction which the rays have on entering the eye, the object... | |

...succession of images is that here indicated. 69. Position and Character of Images in Plane Mirrors.— The image in a plane mirror appears as far behind the mirror as the object is in front of it. This follows immediately from the law which announces the equality of the angles of incidence and reflexion.... | |
