**Diffused Reflection**
Diffused reflection is a type of reflection that occurs when a ray of light strikes a rough or irregular surface and reflects in many different directions. It is also known as scattered reflection. Unlike regular reflection, where the light rays bounce off a smooth surface at the same angle, diffused reflection causes the light rays to scatter in various directions.
**Explanation**
Diffused reflection occurs on a rough surface because the irregularities on the surface cause the light rays to bounce off in different directions. These irregularities can be in the form of bumps, scratches, or any other roughness on the surface. When a ray of light strikes the surface, it interacts with these irregularities and gets scattered in many different directions.
**Comparison with Other Options**
a) Concave Mirror: A concave mirror is a curved mirror with a reflective surface that curves inward. It is commonly used in reflecting telescopes and makeup mirrors. When a ray of light strikes a concave mirror, it follows the law of reflection and bounces off at an angle equal to the angle of incidence. This is not diffused reflection but rather regular reflection.
b) Convex Mirror: A convex mirror is a curved mirror with a reflective surface that curves outward. It is commonly used in rear-view mirrors and security mirrors. Similar to a concave mirror, when a ray of light strikes a convex mirror, it follows the law of reflection and bounces off at an angle equal to the angle of incidence. Again, this is not diffused reflection but regular reflection.
c) Plane Mirror: A plane mirror is a flat mirror with a reflective surface. It is commonly used in bathrooms, dressing rooms, and for decorative purposes. When a ray of light strikes a plane mirror, it follows the law of reflection and bounces off at an angle equal to the angle of incidence. Just like concave and convex mirrors, this is regular reflection and not diffused reflection.
d) Rough Surface: A rough surface, as mentioned earlier, contains irregularities that cause light to scatter in different directions. When a ray of light strikes a rough surface, it interacts with these irregularities and gets reflected in multiple directions. This is diffused reflection.
Therefore, the correct answer is option 'D' - rough surface.
