(show work) Answer_____ GCSE . overall magnification = power of eyepiece × power of objective = 5 × 10 = 50 × the original size overall magnification = power of eyepiece × … Size of image = magnification / size of real object. Magnifying your field of view; 12. Working out magnification: Measure the scale bar image (beside drawing) in mm. Magnification introduction; 9. A typical animal cell; 16. 15. If your answer is greater than 1, that means the image is magnified. Magnification = scale bar image divided by actual scale bar length (written on the scale bar). Calculating the Field of View; Example: Calculating Size of Object From its Microscopic Image . Use the same formula as above. b. How to calculate magnification; 10. Convert to µm (multiply by 1000). How large are cells? 9 Quizzes . Question; Solution; Example: Calculating Actual Size Given of a Structure Given Scale Bar on an Image. For a more enjoyable learning experience, we recommend that you study the mobile-friendly republished version of this course. It is hard to make measurements above 25mm because most eye pieces on a microscope To calculate magnification, use the following formula: magnification = the height of the image ÷ by the height of the object.
