(10) Draw a ray diagram for a 3.0-cm tall object placed 10.0 cm from a converging lens having a focal length of 15.0 cm. (11) Draw a ray diagram for a diverging lens that has a focal length of -10.8 cm when an object is placed 32.4 cm from the lens's surface.

Lens Ray Diagram Name Directions: Use the rules from the Optical Ray Diagram Rules information sheet, follow along with your teacher to draw the ray diagrams for the various cases of optical references. Answer and Explanation: The path of the reflected ray at each boundary can be determined by sketching a normal at the point where the incident ray strikes the mirror surface. Once the normal is constructed the angle of incidence can be measured. For instance, the black dashed line at the location where ray 1 strikes the mirror is the normal line. Guidelines for Rays Falling on the Concave and Convex Mirrors. When a ray strikes concave or convex mirrors obliquely at its pole, it is reflected obliquely. When a ray, parallel to principle axis strikes concave or convex mirrors, the reflected ray passes through the focus on the principle axis.
