The correct option is (a).
Explanation
Reflection of light is the phenomenon where light waves change direction upon striking a surface. This process is governed by the laws of reflection and the fundamental property of the rectilinear propagation of light.
- Statement 1 is Correct: A mirror is a polished surface specifically designed to reflect light. When a light ray strikes a mirror, it bounces off the surface, resulting in a change in the direction of the light.
- Statement 2 is Incorrect: A polished surface reflects most of the light falling on it rather than absorbing it. Absorption is characteristic of dark or opaque surfaces; a surface that absorbs all light would appear perfectly black. Mirrors are highly reflective, not absorptive.
- Statement 3 is Incorrect: Light travels in straight lines, a property known as rectilinear propagation. While reflection changes the direction of the light path, the light rays themselves remain straight before and after striking the surface. They do not curve.
Key Takeaway: Mirrors reflect light by changing its direction, but the propagation of light remains rectilinear (in straight lines).
