Answer 1

Answer:

No, the laws remain same.

Explanation:

No, he laws of reflection still remain the same.

The laws of reflection are:

1) Incident ray, normal and reflected ray line in the same plane

2) Angle made by incident ray and the normal is same as the angle made by reflected ray and normal.

Now in a plane mirror, the normal to the surface is same everywhere on the plane so parallel incident rays cause parallel reflected rays

But if the mirror is spherical then normal at each point is different so parallel incident rays won't cause parallel reflected rays, other than this each law of reflection is still valid.
