- what are the magnification powers of objectives of the microscopes in our classroom?
(low)
(med)
(high)
- calculate the total magnification of an image viewed under low power in our microscope.
- calculate the total magnification of an image viewed under med power in our microscope.
- calculate the total magnification of an image viewed under high power in our microscope.
- calculate the total magnification of a microscope whose ocular lens has a magnification power of 10x and a high power objective lens of 60x.
Question 1
A compound light microscope magnifies images using the ocular (eyepiece) lens and the objective lenses. These two components work together to increase the size of the specimen's image.
In most classroom compound light microscopes, the ocular (eyepiece) lens typically has a magnification power of 10×. This is a standard magnification for the eyepiece to provide a clear initial magnification before multiplying with the objective lens magnification.
For typical classroom microscopes, the low - power objective usually has a magnification of 4×, the medium - power objective is often 10×, and the high - power objective is commonly 40× (or sometimes 100× for oil immersion, but for regular high - power in classroom setups without oil, 40× is common).
