We'll email you at these times to remind you to study. 9 Quizzes . * Multiply the viewing power of the eye piece by the power of the objective used to examine the slide. Field of view; 11. This is important when you want to view an object on the cellular level. Working out magnification: Measure the scale bar image (beside drawing) in mm. overall magnification = power of eyepiece × power of objective = 5 × 10 = 50 × the original size overall magnification = power of eyepiece × … A typical animal cell; 16. Correct. If your answer is between 0 and 1, the image is smaller than the object. What are the key points to observe carefully? The drawing is roughly 7 cm long.
