The best way to demonstrate the laws of reflection involves a narrow, bright beam of light to shine on reflective surfaces; for this a laser works very nicely. But lasers can be hazardous; even if they are not powerful enough to cause burns or damage anything (and it would be foolish to use such a powerful laser for this demonstration), they are usually still bright enough to cause eye injuries.
Thus, if you're going to do this demonstration, it is important to make sure that no one ever looks directly into a laser or shines a laser directly into someone else's eyes. Beyond that, demonstrating the laws of reflection is relatively safe and straightforward: Shine the laser at reflective surfaces at known angles and measure the angle at which it reflectshope I made myself clear if you think the answer is appropriate please mark it is brainliest

Following laws of reflection are valid for smooth surfaces like mirror,still water surface etc. (1)the incident ray, Normal and reflectedray all lie in same plane. (3) angle of incidence is always equal to angle of angle of reflection. The angle of incidence is equal to the angle of reflection.
The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. Furthermore, the angle of reflection is equal to the angle of incidence . Both angles are measured with respect to the normal to the mirror.
