17	When does a concave mirror produce no image?
18	Where is the object placed in front of a concave mirror to produce a reduced, real, inverted image?
19	Where is the object placed in front of a concave mirror to produce a real, inverted image that is the same size as the object?
20	True or False. The minimum length mirror a person needs to completely view his body (from head to toe) equals half his height.
