If 15 mm size object is observed under light microscope using 5X eyepieces and 10X objective, its magnified image size will be:
Correct answer: C. 750 um
- A. 250 um
- B. 50 um
- C. 750 um
- D. 500 um
Explanation
To calculate the total magnification of an object observed under a microscope, you need to multiply the magnification of the eyepiece (ocular lens) by the magnification of the objective lens. In this case, you're using a 5X eyepiece and a 10X objective lens. Total magnification = Eyepiece magnification × Objective magnification Total magnification = 5X × 10X Total magnification = 50X So, the object will be magnified 50 times under the given microscope setup. If the object's actual size is 15 mm, its magnified image size will be: Magnified image size = Actual size × Total magnification Magnified image size = 15 mm × 50X Magnified image size = 750 mm The magnified image size will be 750 mm.
