A _______________reflection takes place when the light beam falls on a highly polished surface.

Regular reflection:

1. When we hold a plane mirror in front of us we see our faces in it.
2. This is because the entire light that falls on the surface is reflected in a definite direction.
3. Such a reflection is called regular reflection.
4. It takes place only when the light beam falls on a smooth highly polished surface.

Hence, a regular reflection takes place when the light beam falls on a highly polished surface.
