A system of two lenses forms an image of an arrow at x = x3 = 57.4 cm. The first lens is a diverging lens located at x = 0 and has a focal length of magnitude f₁ = 11.5 cm. The second lens is located at x = x₂ = 25.4 cm and has an unknown focal length. The tip of the object arrow is located at (x,y) = (X。› Y。) = (-36 cm, 20.6 cm).

Transcribed Image Text:A system of two lenses forms an image of an arrow at x = x3 = 57.4 cm. The first lens is
a diverging lens located at x = 0 and has a focal length of magnitude f₁ = 11.5 cm. The
second lens is located at x = x₂ = 25.4 cm and has an unknown focal length. The tip of
the object arrow is located at (x,y) = (xo, Yo) = (-36 cm, 20.6 cm).

3) What is f2, the focal length of the second lens. If the lens is a converging lens, f2 is
positive. If the lens is a diverging lens, f2 is negative.

4) What is y3, the y-coordinate of the image of the tip of the arrow formed by the two
lens system?

5) The positions of the two lenses are now interchnaged (i.e., the second lens is moved
to x = 0 and the diverging lens is moved to x = x2 = 25.4 cm). What is the nature of
the final image in this new system?
