Hi can anyone help me with this question: Number 1) d) The one about re-arranging the magnification question, for some reason I can't seem to get the same answer as the mark scheme, I have measured the image size as 2cm and I have converted it into micrometres, however when you divide 50,000 (the magnification) by that number it doesn't get the answer as presented in the mark scheme, if anyone can help, thank you.
