These are the mirrors that are utilised the most. These are spherical mirrors bent outwards that provide a virtual, reduced, and erect image of a real thing. These are inwardly curved spherical mirrors, and the picture they produce is depending on the position of the object.Ī flat surface is referred to as a plane. A plane mirror is just a mirror with a fully flat, smooth surface. This prevents the image from becoming distorted. A fun-house mirror, on the other hand, maybe the polar opposite, with its different bends and curves making the image look silly.Ī sphere is a 3D replica of a perfect circle, with a constant radius and a consistent curve all the way around. So a spherical mirror is a sphere-shaped mirror with a continuous curve and constant radius of curvature. Spherical mirrors can be convex or concave depending on which side the mirrored surface is placed on. A convex mirror is a spherical mirror that has its reflecting surface on the outside of the spherical curve. On the other hand, a concave mirror is a spherical mirror with a mirrored surface on the inside of the curve. Virtual, upright representations the same size as the object are created by plane mirrors. By the way, virtual simply implies that the picture is produced behind the mirror rather than in front of it. The angle of reflection and incidence are equal. The incident ray, reflected ray and normal point of reflection lies in the same plane. The angle of incidence is denoted by 'i' and angle of reflection is denoted by 'r'. The rule of reflection is valid to all types of reflecting surface.
