    Study Notes

    The law of reflection is a fundamental concept in physics that describes how light behaves when it hits a reflective surface and bounces back. According to this law, the angle of incidence (θi) of a light ray striking the surface is always equal to the angle of reflection (θr) at that same point. This means the reflected light follows the same path as the incident light if observed along the same direction.

    When a ray of light strikes a mirror, the angle of incidence determines the angle at which the reflected ray leaves the mirror. The normal line, perpendicular to the mirror's surface, divides the angles between the incident and reflected rays into two equal parts. The angle measured between the incident ray and the normal line is known as the angle of incidence, while the angle measured between the reflected ray and the normal line is known as the angle of reflection.

    For example, consider a light beam hitting a plane mirror at an angle of 30 degrees relative to the mirror's surface. According to the law of reflection, the angle of reflection will also be 30 degrees but relative to the normal line, not the mirror's surface. This is why the angle of incidence and reflection are complementary, and the sum of both angles will add up to 90 degrees.

    In practice, the laws of reflection can be verified experimentally using a flat sheet of paper placed on a surface and a straight line drawn across its center. When viewing the line through the mirror at various positions, the images of points on the line appear to move parallel to each other, demonstrating the validity of the law of reflection.
