I'm Talking 'Bout the Robot In the Mirror...

Q19. Since the image is clearly magnified, this must be a concave mirror. Only concave mirrors can magnify objects. This occurs when an object is placed between the mirror and its focus.

P4. The easiest way to solve this problem is to extend the top ray through the mirror. You then obtain a pair of similar triangles. Solving the proportion, x = 75.9 cm

P11. A picture is worth a thousand words:

P16. Leave out part b, we will discuss the equations of ray tracing tomorrow in class. Make a scale sketch of the situation on graph paper (notice it is a convex mirror!) - you should obtain that the distance of the image is between 6 and 7 centimeters on the far side of the mirror, and the image should be upright.
