an object is placed 15 cm from a convex mirror of curvature 90cm calculate the image position and the magnification |
|
Answer» Answer: Convex MIRROR: Radius of Curvature=+90cm (GIVEN) So focal length =+45 cm (f=R/2) u=-15 cm (given) Using mirror formula, 1/f = 1/v + 1/u 1/45 + 1/15 = 1/v v=45/4 cm So, image distance is 45/4 cm. Nature: Virtual Erect m=-v/u =3/4. |
