yes i know that, but there is a question that i saw last night while i was gng thru some past papers, and there was a magnified picture of a pollen grain and underneath it there was a question asking us to calculate the real size of the pollen grain and by how many times it has been magnified, thts wat i wanna knw, hw can i calculate magnification? :S

twilight:
measure the diameter of the pollen grain that is magnified .. using ur ruler
then divide this by the real size to get magnification
u can attach the question paper .. i'll go thru it and tell u

LaRi:
