The distance of the object from the lens is 30 cm. Find the 16:06 Important Numericals: (Que.3 to 5) Que.3 - An object is placed at a distance of 25 cm away from a converging mirror of focal length 20 cm. Discus the effect on the nature and position of the image if the position of the object changes from 25 cm to 15 cm. Justify your answer without using mirror formula. 28:05 Important Numericals: (Que.6 to 8) Que.6 - It is desired to obtain an erect image of an object, using concave mirror of focal length of 12 cm. 53:00 Important Numericals: (Que.9 & 10) Que.9 - List the new Cartesian sign convention for reflection of light by spherical mirrors. Draw a diagram and apply these conventions for calculating the focal length and nature of a spherical mirror which forms a 1/3 times magnified virtual image of an object placed 18 cm in front of it. 01:04:16 Website Overview ======================================================= Why study from Magnet Brains?
