Unformatted text preview: A. Because reflected rays from the stick refract at the surface water-air B. Because the water acts as a converging lens C. Because the light disperses when passing the surface water-air A ray parallel to the axis of a concave mirror A. Is reflected along the radius thru the center of the curvature of the mirror B. After reflection passes through the focal point C. Is reflected also parallel to the axis A ray passing thru a focal point of a thin converging lens A. Is refracted parallel to the lens axis B. Does not deviate appreciably C. Refracts to pass through the second focal point...
