Q. What is the focal length of a convex lens of focal length 30 cm in contact with a Concave lens of focal length 20 cm ? Is the system a converging or a diverging lens?
Ignore thickness of the lenses.
Answer
A Focal length of the convex lens f1 = 30cm
A Focal length of the concave lens f2 = - 20cm
A Focal length of the system of lenses = f
The equal focal length of a system of two lenses in contact is given as
Hence the focal length of the combination of lenses is 60 cm. The negative sign specifies that the system of lenses acts a diverging lens.
