Question

(a) The magnification of a body of size 1m is 2, then find the height of image.
(b) Focal length of 2 lenses are 40cm and – 20 cm respectively. Find the power and nature of combined lens.

Answer 1

Answer:

Multiply the magnification of the lenses together. For example, if the eyepiece magnification is 10x and the objective lens in use has a magnification of 4x, the total magnification is 10 × 4 = 40. The total magnification of 40 means that the object appears forty times larger than the actual object.
