In regular reflection, the angle of incidence is …………. the angle of reflection
The answer is: equal to the angle of reflection.
When talking about regular reflection, this reflection occurs when light bounces off a smooth, flat surface. In this type of reflection, the angle of incidence, which means the angle of inclination of the light from the source to the surface, is the same as the angle of reflection at which the light bounces off the surface. This means that the light bounces off as a plane mirror. In the case of uniform reflection, the angle between the line perpendicular to the surface and the light ray must be identical, and this is known as the first law of reflection. It is important to note that this type of reflection only occurs when the surface is smooth and flat, whereas when the surface is rough there is an irregular reflection.
