Has the image a fixed position no matterfrom what position you view it in front of the mirror?Connect A and A\ B and B; C and C.

EXPERIMENT H Question.—When looking at a pond of water at anangle, why does its depth appear less than it really is? Apparatus.—Semi-circular glass vessel, the planeside being opaque with a vertical slit in the centerthrough which light may pass, the half-circle beingtransparent and graduated in degrees; candle; com-pass. Directions.— Fill the vessel one-third full of waterand place the lighted candle in the position shown inthe diagram. The incident beam of light CO will passthrough the slit 0. The part of the beam above thewater will not be refracted and will pass in a straightline to A. The part striking the water will be Miscellaneous Experiments 99. refracted and will go to B. Take the readings of A andB in degrees, counting from X, the zero of the scale. With compass, rule, and sharp pencil, lay off on apage of your notebook an accurate reproduction ofthe half-circle and the lines CO, OA, and OB. Drawthe line XY perpendicular to the plane side of thevessel at 0. The angle CO Y is known as the angle ofincidence. The angle BOX is known as the angleof refraction. The angle AOB is known as theangle of deviation. By reading A to get the measure-ment of angle A OX we get the measurement of angleCOY. Why? Make another trial with the candle nearer to F, andstill another with the candle at Y.

In what direction is thelight wave bent, toward, or away from a line perpen-dicular to the surface? Which
