Practice Andhra Pradesh SSC (Class 10) Reflection of Light at Curved Surfaces in the app →The mid point (geometric centre) of a spherical mirror is called itsFor a concave mirror the focus and centre of curvature lieThe relation between radius of curvature R and focal length f of a spherical mirror isWhich mirror converges a parallel beam of light to a real focus?The mirror commonly used as a rear view mirror in vehicles is aA ray parallel to the principal axis, after reflecting from a concave mirror,A ray aimed at the centre of curvature of a concave mirror retraces its path because itAn object placed beyond the centre of curvature of a concave mirror forms an image that isWhen an object is placed between the pole and focus of a concave mirror, the image isThe mirror formula relating object distance u, image distance v and focal length f isThe magnification produced by a spherical mirror is given byAn object is placed 25 cm in front of a concave mirror of focal length 15 cm. The image distance v isFor that mirror (u = 25 cm, object height 4 cm, v = -37.5 cm), the image height isAccording to the sign convention, the focal length of a concave mirror is taken asWhich spherical mirror always forms a virtual, erect and diminished image for every object position?A concave mirror is used in a solar cooker mainly because it canA negative value of magnification for a mirror indicates that the image isFor a concave mirror, when the object is exactly at the centre of curvature, the image formed isA spherical mirror has a radius of curvature of 30 cm. Its focal length isThe normal at any point on a spherical mirror lies along the line joining that point to theThe focus of a convex mirror isFor a concave mirror, when the object is placed exactly at the focus, the image is formedA real image formed by a mirror is one thatFor a concave mirror, when the object is placed at the centre of curvature, the magnification isA convex mirror gives a wider field of view than a plane mirror of the same size because its image isA concave mirror forms an erect image only when the object is placed
