A) An object is placed at a distance of 30 cm from a concave mirror of focal length 15 cm. Write characteristic of the images formed. Also draw its ray diagram (5 marks) |

Answer» Answer: Explanation: FORMULA related to focal length f, object-to-mirror distance u and image-to-mirror distance v is given by solving the above eqn for v, we get v = 30 CM
(1) image is formed at a distance 30 cm from concave mirror (2) SINCE image distance and object distance are same ( both are at 2F), MAGNIFICATION = 1 Image and object are same size. (3) image is real (4) image is inverted |
