What is the rule for focusing if you switch to the 40x lens? 2. Calculate the sizes of the following cells. Not all cells are viewed at 40x so use the following table to calculate the size of your cells. 4x 1 reticular unit = .025 mm 10x 1 reticular unit = .01 mm 40x 1 reticular unit-.0025 mm 4 points A) Cell 1 on 10x=8 reticular units B) Cell 2 on 40 x = 28 reticular units mm mm Which one is actually larger?
