Question

A specimen is 0.2 mm long. Calculate the length of its image if it magnified by 1000 times.

Answer 1

200 cause 0.2 times 1000 is 200

Answer 2

magnification is equal to the ratio of image height(H) to the object height(h)
Therefore,

m=H/h

1000=H/0.2

H = 1000 * 0.2

So,
Image height (H) = 200 mm
