Question

What type of mirror should be used
(a) as a shaving mirror?
(b) as a shop security mirror?

Answer 1

Conclusion:

(a) For shaving mirror, we used Concave mirror

(b) For shop security mirror, we used convex mirror

Explanation:

(a) we used concave mirror for shaving because our face is closer to mirror and held between Focus and pole so the image will be formed in bigger size, erected and virtual. Concave mirror is used to focus the light so that we can used the concave mirror for shaving mirror.

(b) We require such mirror which can cover more area, distant objects, diminish the actual size of objects and formed the image erected and virtual. so we used the convex mirror, in this case image formed between pole and focus of the convex mirror and it is also used for diverging the light.

Answer 2

Inner Side Reflecting Surface is Concave Mirror

Explanation:

If the inner side of the spherical mirror is reflecting, it is called a concave mirror.

If the outer side of the spherical mirror is reflecting, it is called a convex mirror.

Concave mirrors can form inverted and real images and also virtual and erect images.

So,

(a) For shaving mirror, we used Concave mirror

(b) For shop security mirror, we make use of convex mirror
