Reflection of Light Rays, Examples and Solutions Reflection of Light Rays on a Reflecting Surface. When a light ray strikes a surface separating two media with different optical properties, part of the light energy is reflected back to the media where it coming from. When light strikes a perfectly reflecting surface, such Selina Concise Physics Class 9 ICSE Solutions Reflection Exercise 7(A) Solution 1S. The return of light into the same medium after striking a surface is called reflection. Solution 2S. Black silvered surface reflects most of the light incident on it.
