Question

7. A type of reflection where light rays reflected
from a perfectly smooth surface are parallel
to one another.​

Answer 1

Answer:

In regular reflection, a parallel beam of incident light is reflected as a parallel beam in one direction. In this case , parallel incident rays remain parallel even after reflection and go only in one direction and it occurs from smooth surfaces like that of a plane mirror or highly polished metal surfaces

Answer 2

In regular reflection, a parallel beam of incident light is reflected as a parallel beam in one direction. In this case , parallel incident rays remain parallel even after reflection and go only in one direction and it occurs from smooth surfaces like that of a plane mirror or highly polished metal surfaces. Thus, a plane mirror produces regular reflection of light. Since the angle of incidence and the angle of reflection are the same or equal, a beam of parallel rays falling on a smooth surface is reflected as a beam of parallel light rays in one direction only.
