Curved Mirror A curve is part of a circle. Therefore the centre of the circle will also be the centre of the curve and is called the centre of curvature, and the radius of the circle will be equal to the radius of the curve, called the curvature radius. Important Terms All rays parallel to … Read more

(Reflection of light on a plane mirror) Plane Mirror Images in plane mirrors Figure to the right shows how, by reflecting light, a plane mirror forms an image of a point source of light such as a small light bulb. The image forms in a mirror is Upright Virtual Laterally inverted Same size as the … Read more

Reflection of Light Note: Both the angle of incident and angle of reflection must be measured from the normal. Laws of Reflection The law of reflection state that The angle of incidence is equal to the angle of reflection; the ray leaves the surface at the same angle as it arrives. The incident ray, the … Read more
