Understanding the Reflection of Light: Ray Optics and Concave Mirrors

[Docscientist]

Why a ray of light passing through the centre of curvature of a concave mirror,gets reflected along the same path?

Why a ray of light passing through the centre of curvature of a concave mirror,gets reflected along the same path?

one should apply the laws of reflection to get answer to your question!
moreover the ray is not passing through but its incident along the radius then it returns after reflection on the same path.

Where does the normal (perpendicular) to the surface of the mirror at the point where the ray comes onto the mirror lie?
