Remember that a concave mirror forms part of a hollow sphere. Any line joining the centre of the sphere (the centre of curvature of the mirror) and any point on the mirror will be normal to the reflecting surface of the mirror. Therefore A ray of light passing through the principal axis will be normal…… Continue reading Why the ray of light passing through the centre of curvature of a concave mirror behave as normal while it doesn’t behave as normal when it passes through other points on the principal axis?
(Collected from Previous Board Question Papers and CBSE Sample Papers andGuess Papers made by experienced teachers) Where does centre of curvature of a spherical mirror lie? Name two important properties of a magnet. How is 1 ohm related to ampere and volt? Draw neat ray diagrams to illustrate the formation of images due to a beam of light incident…… Continue reading Commonly asked questions for AISSE (CLASS X CBSE) Physics (Set – 1)
