note
Countable and uncountable. In numbers: magnification ×10 means the image is 10 times as long and 10 times as wide as the real thing (but not 10 times the area – area grows 100 times). To find a real size, divide the image size by the magnification. Verb: magnify. Not the same as «magnitude» (size, especially of earthquakes).
