Back to paper

The reflection on a bathroom mirror, the lake, and the glare on a pair of glasses are caused by which type of reflection?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. Specular reflection.

Specular reflection occurs when light reflects off a smooth, shiny surface (like a mirror, lake, or glasses) at a definite angle, creating a clear and sharp image. This type of reflection follows the law of reflection, where the angle of incidence equals the angle of reflection.

Other Options:

  1. Diffused reflection: Happens on rough surfaces (e.g., paper, walls), scattering light in all directions, preventing a clear reflection.

  2. Glossy reflection: A mix of specular and diffused reflection, seen on slightly textured shiny surfaces (e.g., glossy paint).

  3. Multiple reflection: Occurs when light reflects between two or more surfaces (e.g., mirrors facing each other).

Specular reflection best explains reflections in mirrors, lakes, and glasses due to their smooth surfaces.
