1)For the diverging lens:
1/f = 1/v + 1/u
here, f = focal length of the diverging lens= -29 cm
v = image distance from the diverging lens.
u = object distance from the diverging lens= 46 cm
Now, 1/(-29) = 1/v + 1/46
=> 1/v = -(75/1334)
=> v = -17.79 cm
The distance of the image from the diverging lens= (-17.79) cm
We know,
hi/ho =- v/u
=> hi = -14×(-17.79/46)
=> hi = 5.41 cm
The height of the image is 5.41 cm
On the left side of the diverging lens the image will be formed.
2) The object distance for the converging lens= (59+17.79)= 76.79 cm
For the converging lens:
1/20 = 1/v + 1/(76.79)
=> 1/v = 0.0398
=> v = 27.04 cm
The distance of the image from the converging lens is 27.04 cm
The final image will be located on the right side of the converging lens.
The magnification= (-27.04/76.79)= -0.352
The final height of the image = (-0.352)×(5.41) = -1.905 cm
The final image will be real image.
Please comment if you have any doubt and like if it helps.
Happy learning.
