Need help with later magnification and location!
Two lenses, with = +20.0 and = +30.0 , are placed on the axis, as shown in the figure. An object is fixed 50.0 to the left of lens 1, and lens 2 is a variable distance to the right of lens 1.
Part A
Find the lateral location of the final image relative to lens 2 for the case = 100 .
=54.5
Correct
Part B
Find the lateral magnification of the final image relative to lens 2 for the case = 100 .
=
One attempt remaining; Try Again
Part C
Find the lateral location of the final image relative to lens 2 for the case = 30.0 .
=3.00
Correct
Part D
Find the lateral magnification of the final image relative to lens 2 for the case = 30.0 .
=
Try Again; 4 attempts remaining
Part E
Find the lateral location of the final image relative to lens 2 for the case = 0.
=
Try Again; 5 attempts remaining
Part F
Find the lateral magnification of the final image relative to lens 2 for the case = 0.
=
Part G
Show that your result for part E agrees with the relation for the effective focal length of two lenses in contact, .
