An object is placed 18 cm to the left of a converging lens of focal length 27 cm. A diverging lens of focal length 10 cm is 25 cm to the right of the converging lens. Find the position and magnification of the final image?
The nickel's image has four times the diameter of the nickel when the lens is 2.70 cm from the nickel. Determine the focal length of the lens?
Calculate the angular spread of a laser beam due to diffraction if the beam emerges through a 2.90mm diameter mirror. Assume that lambda = 686nm.

The image of a very distant car is located 24 cm behind a convex mirror. What is the radius of curvature of the mirror?
A person stands 3.4m in front of a wall that is covered floor-to-ceiling with a plane mirror. His eyes are 2.0m above the floor. He holds a flashlight between his feet and manages to point it at the mirror. At what angle of incidence must the light strike the mirror so the light will reach his eyes?
Which kind of spherical mirror, concave or convex, can be used to start a fire with sunlight? For the best results, how far from the mirror should the paper to be ignited be placed?
For an image formed by a concave mirror to be a point, the object must be: A) between the principle focus and the mirror B) at the center of curvature C) at an infinite distance D) at the principle focus
