👉 Reflection math is a branch of mathematics that studies the properties and behaviors of reflections, particularly in geometric contexts. It involves analyzing how shapes and figures change when reflected across lines, planes, or other surfaces. Key concepts include the angle of incidence equals the angle of reflection, where the angle between the incident ray and the normal (a line perpendicular to the reflecting surface) equals the angle between the reflected ray and the normal. This principle is crucial in optics, physics, and engineering, helping to predict and explain phenomena such as mirror images, light behavior in lenses, and the symmetry of geometric figures. Reflection math also delves into more complex scenarios like multiple reflections and their applications in designing optical systems and understanding wave patterns.
