Magnification Task Show your working out in your book. 1. What is the total magnification of a microscope with an eyepiece magnification of x 10 and an objective lens magnification of x 30? 2. Laila wants to observe an onion cell under the microscope. What is the total magnification if the eyepiece magnification of x 40 and an objective lens magnification of x 20? 3. What is the total magnification of a microscope with an eyepiece magnification of x 40 and an objective lens magnification of x 30? 4. Challenge: What is the objective lens magnification if the total magnification is: x 200 and the eye piece is x 5. www. astreadearne. org
