HOME EXPERIMENT: THE PU PIL 1. Look at the central transparent area of someone's eye, the pupil, in normal room light. Estimate the diameter of the pupil. Now turn off the lights and darken the room. After a few minutes turn on the lights and promptly estimate the diameter of the pupil. What happens to the pupil as the eye adjusts to the room light? Explain your observations. ACTIVITY 1B: SOLVE ME 1. A 14.5 cm high object is placed 50.0 cm in front of a concave mirror with radius of curvature equal to 30.0 cm. Determine the distance, height, and image formed by the mirror. 2. Two convex lenses A and B, each of focal length 25.0 cm, are placed 80.0 cm apart on the same axis. A 12.0 cm high object is placed 50.0 cm in front of lens A. Find the position, nature, and size of the final imaga
