3. A concave spherical mirror has a radius of20cm. A real object is placedon the optical axis 15cm
from the mirror.
a. Compute where the image is and describe it (realorvirtual, upright or inverted, enlarged or
diminished). (10)
b.Construct a ray tracing diagram. (try to draw it carefullytoscale).
A magnifying glass is a converging lens, which could be used to make a real image of an object. A small lightbulb is placed 25.0 cm in front of the convex lens with a focal length of 10.0 cm.
Draw a ray-tracing diagram to find the position of the image formed by the lens.
