The power of a microscope lens is the amount of magnification the lens gives. For example, a 10 X lens magnifies objects 10 times. How many times is an object magnified if it is viewed with both a 5 X lens and a 30 X lens ?
35 times
150 times
60 times
350 times
A
35 times
B
60 times
C
150 times
D

The total magnification given by two or more lenses used at the same time is equal to the product of the powers of the lenses. You may understand it by noting that the second lens magnifies the image from the first lens and that the image from the first lens is already magnified. So, the object is first magnified 5 times and then is magnified 30 more times thus resulting in a total magnification of 150 times
XT=X1×X2
=5×30=150times, Hence Option C is correct.
