False Statement: Most of the engineering materials have rough surfaces, and these rough surfaces give regular (specular) reflections.
Explanation:
Reflection is the process where incident light or radiation bounces back from a surface. There are two types of reflections: diffuse reflection and specular reflection. Diffuse reflection occurs when the incident light or radiation is scattered in different directions, while specular reflection occurs when the incident light or radiation is reflected in a single direction.
Most engineering materials have rough surfaces, which means that when light or radiation interacts with these surfaces, it is scattered in various directions due to the irregularities on the surface. This results in diffuse reflection rather than specular reflection.
Diffuse reflection is the reason why we can see objects from different angles because the scattered light reaches our eyes from various directions. On the other hand, specular reflection occurs on smooth surfaces where the incident light or radiation reflects in a single direction, like a mirror.
Therefore, the false statement is option 'D' - Most of the engineering materials have rough surfaces, and these rough surfaces give regular (specular) reflections.
Summary:
- The false statement is option 'D'.
- Most engineering materials have rough surfaces, which result in diffuse reflection rather than specular reflection.
- Diffuse reflection occurs when incident light or radiation is scattered in different directions, while specular reflection occurs when incident light or radiation is reflected in a single direction.
- Diffuse reflection is the reason why we can see objects from different angles, while specular reflection occurs on smooth surfaces like mirrors.
