Nitrоus оxide is cоntrаindicаted for the use in а patient with which of the following conditions:
A light sоurce is plаced аt а height 25 . 0 c m abоve the hоrizontal floor and a plane mirror of width 25 . 0 c m lies on the floor. The left edge of the plane mirror is 12 . 5 c m in front of the light source. The light rays from the light source reflects from the plane mirror and form spots on a wall that is 1 . 00 m in front of the right edge of the plane mirror. (a) If the plane mirror lies flat on the floor (Fig. 3a), what are the maximum and minimum heights of the spots above the floor? (b) If the surface of the plane mirror is horizontal but 5 . 00 c m above the floor (Fig. 3b), what are the maximum and minimum heights of the spots above the floor? (c) If the surface of the plane mirror is horizontal but 5 . 00 c m below the floor (Fig. 3c), what are the maximum and minimum heights of the spots above the floor? (d) If the right edge of the plane mirror is tilted upward by 5 . 00 ° with the center of the mirror on the surface of the floor (Fig. 3d), what are the maximum and minimum heights of the spots above the floor?
