Question

This is my final attempt on this question please help me answer this correctly!!

Two converging lenses with focal lengths of 50 cm and 19 cm are 10 cm apart. A 2.4-cm-tall object is 25 cm in front of the 50-cm-focal-length lens.

Part A

Calculate the distance between the image and 19-cm-focal-length lens.

Express your answer to two significant figures and include the appropriate units.

(correct answer to part A is d=28cm) so I get that

Need help with part B

Part B

Calculate the image height.

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

u=25 cm

f_2=28 cm

using 1/f=1/u+1/v

v =-250 cm

M = v/u = -10

image height = -10 * (2.4 cm)= -24 cm
