Could someone please help me with this?

If the two lenses in the figure are separated by 10.7 cm locate the final image and find the magnification of the system. CHint: The object for the second lens is virtua (U se the necessary information from the Practice It portion of the problem.) 5.48 x Remember that a multiple lens system is a series of single lens systems with the image of one lens acting as the object for the next lens in line. cm 64 To find the total magnification of a multiple lens system, multiply together the magnification caused by each of the individual lenses.

Explanation / Answer

We have

1/f = 1/u+1/v

1/10 = 1/30 +1/v

v = 14.99 cm = 15 cm

Now, u = 15 cm

1/v = 1/20-1/15

V = -60 cm, Final Image

B)

Magnification =m1*m2= (First image distance/first object distance)*(Second image distance/ Second object distance)

Magnification = (15/30)*(60/15) = 2
