Question

Light compound microscope with 15X eye piece lense and 45X objective lense will have a magnification of

• A. 2000
• B. 675
• C. 1000
• D. 45

Answer 1

The correct option is B 675

In light compound microscope in order to ascertain the total magnification when viewing an image with a compound light microscope, take the power of the objective lens which is at 4x, 10x or 40x and multiply it by the power of the eyepiece which is typically 10x. Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed. So, light compound microscope with 15X eye piece lense and 45X objective lense will have a magnification of 675.
