eli5: What is the difference between a mirror and a white object?

1.05K viewsOtherPhysics

I mean, what does a white object do? Absorbs nothing, reflects all light back.

What does a mirror do? Absorbs nothing, reflects all light back.

Having the same characteristics, how does a mirror reflect an image and a white object, a white texture?

Mirror is flat so all light bounces back in one direction. 

White surface is very rough (at small scale) so light bounces in all sorts of directions
