Answer:
Focal length is 6.67 cm.
Explanation:
Object distance, u, from the lens = 10 cm
Image distance, v, to the lens = 10 cm + 10 cm
= 20 cm
Apply the lens formula to determine the focal length, f, of the lens.
= +
= +
=
=
Find the inverse of both sides, so that;
f =
= 6.67
f = 6.67 cm
The focal length of the lens is 6.67 cm.
