Question

1. Why can we not see our clear image in an old mirror ?
2. How is an image more reliable than a shadow ?​

Answer 1

Answer:

We cannot see the clear image in old mirror as it's surface becomes uneven and because of uneven surface, some fraction of light is unevenly reflected.

An image is more reliable that a shadow in that an image is present with any kind of lighting while a well defined shadow is only present with directional lighting. An image also provides far more information.
