Consider the following:1. Refraction2. Reflection3. DiffractionWhich ...
- When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light. The incident light ray which lands upon the surface is said to be reflected off the surface.
- The ray that bounces back is called the reflected ray. If a perpendicular were to be drawn on a reflecting surface, it would be called normal. The figure below shows the reflection of an incident beam on a plane mirror.
- Image formation on a mirror is caused by reflection. Refraction and diffraction have no role to play in it.

Consider the following:1. Refraction2. Reflection3. DiffractionWhich ...
Reflection is the only necessary process for image formation in a mirror.
Explanation:
When light falls on a mirror, it undergoes the process of reflection, which is the bouncing back of light rays from the surface of the mirror. This is the fundamental process that allows us to see images in a mirror. The other two processes, refraction and diffraction, are not involved in image formation in a mirror.
Refraction:
Refraction is the bending of light as it passes from one medium to another. It occurs when light travels from a medium with one refractive index to a medium with a different refractive index. However, mirrors are made of materials with a single refractive index, such as glass or metal, and do not involve any change in the medium. Therefore, refraction does not play a role in image formation in a mirror.
Diffraction:
Diffraction is the bending of light waves around obstacles or through narrow openings. It occurs when light encounters an edge or a slit, causing the light waves to spread out. However, mirrors do not have any edges or slits that would cause diffraction. The surface of a mirror is usually smooth and flat, and therefore, diffraction does not contribute to image formation in a mirror.
Conclusion:
In conclusion, only the process of reflection is necessary for image formation in a mirror. Refraction and diffraction do not play a role in this process. When light rays hit the surface of a mirror, they bounce off and form an image due to the reflection process. This is why the correct answer is option 'B', which states that only reflection is necessary for image formation in a mirror.
