Detailed Solution
Irregular reflection, like all other forms of reflection, follows the fundamental laws of reflection. In physics, the laws of reflection apply universally—whether it is regular reflection, diffused reflection, or irregular reflection on rough surfaces. This means that even in irregular reflection, the angle of the reflected ray is always equal to the angle of the incident ray, measured with respect to the normal. The normal is a line perpendicular to the surface at the point of contact.
Irregular reflection occurs when light encounters a surface that is not smooth, such as a rough wall or a frosted glass window. Despite the surface’s uneven texture, the basic principle remains: the incident angle equals the reflected angle at every microscopic point where light strikes. Because the surface irregularities cause light to reflect in multiple directions, the reflection appears scattered and not uniform. However, each individual ray still adheres to the laws of reflection.
In conclusion, the laws of reflection are not limited to smooth surfaces; they govern all reflective interactions. Irregular reflection, though scattered in appearance, still operates under these universal principles, ensuring that the incident angle and reflected angle remain equal at every point of contact on the uneven surface.
