Question

what should be the position of the object when a concave mirror is to be used

A) shaving mirror
B) in torches producing a parallel beam of light​

Answer 1

Answer:

A concave mirror produces a virtual and magnified image when the object is placed very close (between P and F, or between C and F) to it. This position should be used for shaving mirror. 2) When the object is placed at the focus, it generates a parallel beam of light. So for torches the object should be at F.
