What is the magnification of the image in a microscope using a 20X ocular and a 100X objective?
Name and show the equation for the the limit of resolution. What happens to the lr when you use an objective with a lower NA, or light source with a shorter wavelength
Homework Answers
Magnification of microscope = magnification of occular lenses × magnification of objective lenses = 20 × 100 = 2000
Limit of resolution = 0.61 × wavelength of light used / numerical aperture
Limit of resolution is the minimum distance between two objects so, that they can be seen as two separate objects. Resolving power is inversely proportional to limit of resolution and is the ability of a microscope to resolve two closely placed objects as two separate objects.
If the angle of numerical aperture is decreased, than limit of resolution will increase or the distance between two objects that can be resolved will also increase. So, if we want to increase resolving power of a microscope, than we need to increase numerical aperture.
Please rate high.

Imagine you are using a light microscope, like the one shown in your lab procedure, to observe a slide of Spirogyra algae. The magnification of the ocular lens is 10X and the magnification of the objective lens is 40X. What is the total magnification of the Spirogyra when you observe the specimen with the microscope? (Just type the number, don't use any letters)

1.) you place a stage micrometer on a microscope and focus in it so the stage micrometer and ocular micrometer are alighned at zero. you observe that 20 divisions of the ocular micrometer aligns with 0.15 millimeters on the stage micrometer, when using the 40x objective with a numerical aperature of 0.80. the ocular lens (eyepiece lens) has a power of 10x. You then remove the stage micrometer and place a slide containing cells onto the microscope and find that...
