Question

1a. An arrow h₀ = 2.00 cm long is located 77.5 cm from a lens, which has a focal length f = 29.5 cm. If the arrow is perpendicular to the principal axis of the lens, as shown in the figure below, what is its lateral magnification, defined as h_i/h₀?

1b. Suppose instead, that the arrow lies along the principal axis, extending from L₀ = 76.5 cm to L_i = 78.5 cm from the lens. What is the longitudinal magnification of the arrow, defined as L_i/L₀?

2a. A converging lens of focal length 8.07 cm is 20.9 cm to the left of a diverging lens of focal length -6.10 cm. A coin is placed 12.0 cm to the left of the converging lens. Calculate the location of the coin's final image. Draw a ray diagram with the three principal rays for this problem.

2b. Calculate the magnification of the coin's final image.
