if the overall magnification of a series of two lenses is 30x, and one lens magnifies 5x, what is the magnification of the other lens? Calculate
Answer:
Given
Overall magnification M=30 xM=30x
One lens magnification is 5 x5x
suppose the magnification of other lens is yy
A compound lens is made up of series of lenses either of same or of different magnification so
yy is given by
y=\frac{30 x}{5 x}=6 xy=
5x
30x
=6x
If 5 x5x lens is replaced by 7 x7x lens then total magnification is
7 x\times 6 x=42 x7x×6x=42x
