Question

show that concave lens always form virtual and diminished image independent of location
of object.​

Answer 1

Answer:

using the lens formula, show that a concave lens produce a virtual and diminished image independant of the location of object. For a concave lens , Focal length is negative i . ... u < 0 Now , using lens formula , 1 f = 1 v - 1 u or 1 v = 1 f + 1 u = 1 | f | - 1 | u | = - [ 1 | f | + 1 | u | ] < 0 for all values of
