- Lens formula: The expression which shows the relation between object distance (u), image distance (v), and focal length (f) is called lens formula.
Linear magnification (m):
- It is defined as the ratio of the height of the image (hi) to the height of the object (ho).
i.e.
- The ratio of image distance to the object distance is called linear magnification.
i.e.
CALCULATION:
Given: u = - 30 cm and f = 15 cm
Lens formula
v = 30 cm
Linear magnification (m)
