One side of radius of curvature R2=120cm of a convexo-convex lens of material of refractive index n=1.5 and focal ength f1=40 cm is silvered. It is placed on a horizontal surface with the silvered surface in contact with it.Another convex lens of focal length f2=20cm is fixed coaxially d=10cm above 1st lens.A point object on axis give riseto an image coincident with it.Findthe height of the object above the upper lens
Dear student,
Please go through:
Let AB represent an object placed at right angles to the principal axis at a distance greater than the focal length f of the convex lens. The image A1B1 is formed beyond 2F2 and is real and inverted.
OA = Object distance = u
OA1 = Image distance = v
OF2 = Focal length = f
OAB and OA1B1 are similar
But we know that OC = AB
the above equation can be written as
From equation (1) and (2), we get
Dividing equation (3) throughout by uvf
