Determine the distance between the two lenses

Reference no: EM13299557

A beam of parallel light, 1.50 mm in diameter passes through a lens with a focal length of 13.7 cm. Another lens, this one of focal length 22.5 cm, is located behind the first lens so that the light traveling out from it is again parallel.

a) What is the distance between the two lenses?

b) How wide is the outgoing beam?
