What is the difference between a mirror and a white surface?What I know is:
1. A mirror reflects light such that an image is formed. The angles of reflection and incidence are equal. It reflects all wavelengths of light.
2. A white surface reflects all visible wavelengths of light. It causes the light to be diffused.

This list, I think, is right, though not complete.
What I'm wondering about is: Why can't one see his image in a polished white surface. We do see an image, but it does not have the same colours as the object.
