What will be the magnification of image formed when an object is placed at a distance 10 cm infront of it and focal length is 30cm convex mirror? |
|
Answer» U = -30 cm f = -15 cm 1 f = 1 u + 1 v
=> 1 v = 1 f − 1 u
=> 1 v = 1 − 15 − 1 − 30 = − 1 15 + 1 30 = − 2 + 1 30
=> 1 v = − 1 30
=> v = − 30 c m . m = − v u = − − 30 − 30 = − 1
therefore , The image is REAL , inverted and of same SIZE as that of OBJECT |
