Answer 2

Answer:

The paint behind a mirror- (a) stops light from passing through the mirror

The back paint is there to protect the reflecting surface from the back and trap more light. Even if there is no glass or back coating, the polished surface would reflect perfectly.

Explanation:

• Explanation: Mirror backing paint, a colored film-forming material, is applied to the surface of silver mirrors to protect the silver layer from being corroded.
• The back paint is there to protect the reflecting surface from the back and trap more light. Even if there is no glass or back coating, the polished surface would reflect perfectly.
• Reflection of light occurs when light hits a smooth surface that does not absorb any of the light but instead bounces it back off the surface. A mirror is flat, smooth, and polished. When light hits a mirror it is not absorbed but is reflected off at a very predictable angle.

Hence, option number 1 is correct.
