Ordinary optical microscope is often used in biological experiments. If a small object is magnified 50 times by the microscope, "magnified 50 times" here refers to () A. Volume B. surface area C. image area D. length and width
When observing an object with a microscope, the magnification refers to the magnification of the length or width of the observed specimen. Therefore, if the object is magnified 50 times, here "magnified 50 times" refers to the length or width of a small object
