MIRROR OF FORMULA 10 LIGHT REFLECTION & REFRACTION Class 10th Physics (Practice Sheet) 1 Which of the following is the correct formula for the mirror equation? A. 1 f = 1 v + 1 u B. 1 f = 1 u − 1 v C. 1 v = 1 f + 1 u D. 1 u = 1 f − 1 v 2 In the mirror formula, 'f' represents: A. Focal length of the mirror B. Object distance C. Image distance D. Magnification 3 If an object is placed at twice the focal length of a concave mirror, the image formed is: A. Real and inverted B. Real and inverted C. Virtual and inverted D. Virtual and erect 4 The magnification produced by a concave mirror is: A. Always positive B. Always positive C. Positive for real images, negative for virtual images D. Negative for real images, positive for virtual images 5 Which of the following is a virtual image formed by a concave mirror? A. Image formed on a screen B. Image formed on a piece of paper C. Image formed on a wall D. Image formed in a shaving mirror 6 The image of a candle flame placed at a distance of 30cm, space, start text, c, m, end text from a mirror is formed on a screen placed in front of the mirror at a distance of 60cm, space, start text, c, m, end text from its pole. What is the nature of the mirror? Find its focal length. 7 A 6cm object is placed perpendicular to the principal axis of a convex lens of focal length 15cm. The distance of the object from the lens is 10cm. Find the position, size and nature of the image formed, using the lens formula. 8 What is the formula for spherical mirrors for object distance p and image distance q? 9 Calculate the image distance and magnification for a 5.00cm tall object placed 10.0cm from a concave mirror with a focal length of 5.0cm. 10 The focal length of a convex mirror is 10cm and the object distance is 20cm. Determine (a) the image distance (b) the magnification of image.
