Reflection and Mirrors

Which part of a spherical mirror is situated midway between the center of curvature and the vertex?

• CENTER OF CURVATURE

• PRINCIPAL FOCUS

• PRINCIPAL AXIS

• VERTEX

As used in the Law of Reflection, the word normal means

• ANY RAY

• PARALLEL TO THE INTERFACE

• PERPENDICULAR TO THE INTERFACE

• TANGENT TO THE INTERFACE

Which is true about the law of reflection

• The angle at which light rays reflect off a surface is equal to the angle at which the incident rays strike the surface.
