# Explain Why, Though Both a Plane Mirror and a Sheet of Paper Reflect Light but We Can See the Image of Our Face in a Plane Mirror but Not in a Sheet of Paper. - CBSE Class 10 - Science

ConceptLight Reflection and Refraction Introduction

#### Question

Explain why, though both a plane mirror and a sheet of paper reflect light but we can see the image of our face in a plane mirror but not in a sheet of paper.

#### Solution

This is because there occurs regular reflection from a plane mirror, which has a smooth surface. Since the particles of the smooth surface are facing one direction, a beam of parallel light rays falling on it is reflected as a beam of parallel light rays in one direction only. These rays meet when produced backwards to form a virtual image of the light source.
However, in the case of a rough paper, a parallel beam of incident light is reflected in different directions (diffused reflection). So, the light rays don't meet to form an image of the object.

Is there an error in this question or solution?
