Two converging lenses of the same focal length f are separated by distance 2f. The axis of the second lens is inclined at angle θ = 60º with respect to the axis of the first lens. A parallel para axial beam of light is incident from left side of the lens, then -
Text Solution
Verified by ExpertsThe correct answer is:
A
u = – f cos 60 0 f = +f
= 
– 
= 
+ 
– 
= 
v = – f
= cos 60
0 
= x
x = 2f
∴ final image will formed at optical centre of first lens.
