Statement I : Due to diffused or irregular reflection of light, a closed room gets light even if no direct sunlight falls inside the room. Statement I : Irregular reflection, where the reflected rays are not parallel, does not follow the laws of reflection.

Statement I is true because diffuse or irregular reflection occurs when light strikes rough surfaces, causing rays to scatter in many directions [3]. This scattering is essential for illuminating areas not in direct sunlight, such as the corners of a closed room. Statement II is false because the laws of reflection—specifically that the angle of incidence equals the angle of reflection—apply to all types of reflecting surfaces, including irregular ones [2]. In diffuse reflection, the reflected rays are not parallel because the normals at different points on the rough surface are not parallel, not because the laws of reflection are violated. Each individual ray still obeys the law of reflection at its specific point of incidence. Therefore, while the first statement correctly describes a physical phenomenon, the second statement incorrectly claims that irregular reflection does not follow fundamental optical laws.
