- Focal length of lens = 10cm
- Distance of object = 15cm
- Type of lens : concex
- Distance of image and nature of image.
Focal length of convex lens is taken positive and that of concave lens is taken negative.
Distance of image can be calculated by using lens formula..
- v = 30 cm
In order to find nature of image, we need to calculate magnification first.
- m =
- m =
- m = - 2
- Real Inverted
