If a microscope has a resolution of 300 nm and you use it to observe 2 cells that are 320 nm apart, would they look blurry, or
will you be able to see 2 separate cells? Why?
If we observe 2 cells that are 320 nm apart under a microscope that has a resolution of 300 nm we will be able to see 2 separate cells.
Resolution in the microscope means the shortest distance up to which 2 objects or in this case 2 cells can be viewed and distinguished easily. Since this microscope has a resolution of 300nm that means 2 cells can be viewed clearly when they're kept 300nm apart and in this case, it's 320nm apart so it will be clearly visible.

To resolve details of a cell using an ordinary microscope, you must use a wavelength that is about the same size, or smaller, than the details of the cell you want to observe. Suppose you wamt to be able to see the ribosomes, which are about 22.0 nm in diameter. If you use an electron microscope, what is the minimum kinetic energy of the electrons? eV
Be sure to answer all parts. The smallest resolution that a microscope can achieve is generally about half the wavelength of the particle probing the sample. For a visible light microscope, this means the smallest features that can be see are about 300 nm in size. The electrons in an electron microscope behave similar to light in a light microscope, having their own wavelength that can be calculated using the equation: λ = (6.626 × 10−34 J·s) / (m ×...
. You observe plant cells living in various conditions using high power on your microscope. Describe what you would expect to see when examining plant cells taken from a high salt environment compared to those from an isotonic environment. What kind of differences do you expect to see? Why (include osmosis in your explanation)?

Light of wavelength 589 nm is used to view an object under a microscope. The objective lens of the microscope is the lens that gathers light from the object being observed and focuses the light rays in order to form an image of the object. It acts as the aperture of the system, determining its resolution. In this case, the objective lens is circular, of diameter 0.95 cm. Assuming that the resolution of the microscope depends solely on the diffractive...
2. A microscope has a 1.1 cm diameter objective lens with a
focal length of 2.3 mm. The microscope is using light with a
wavelength of 550 nm.
Please help me break down and work through this practice
question so that I can better under the steps and work it out on my
own.

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...
