Question

I mistakenly forgot to write down the magnification of this lobster egg image.

I do know that each division on the graticule is 20 microns, as I calibrated it using another duplicate graticule: the actual sizes of the graticules are 5mm long with 100 divisions, and I lined it up so that the installed graticule in the eyepiece spanned only 40 of the 100 divisions of the graticule on the base plate. I believe this meant the installed eyepiece graticules divisions represented 20 microns.

I can see that the eye spot on the egg is 29 divisions, so it is 580 microns long.

Is it possible to determine the magnification with this information?

Answer 1

Yes, it is possible to determine the magnification with the given information. The magnification can be calculated by dividing the size of the image seen through the microscope by the actual size of the object.

Step-by-step explanation:

Yes, it is possible to determine the magnification with the given information.

To calculate the magnification, we need to find the size of the object and the size of its image in the microscope.

Since each division on the graticule represents 20 microns, and the eye spot on the egg is 29 divisions, we can calculate that the eye spot is 580 microns long (29 divisions * 20 microns/division = 580 microns).

The magnification can be calculated by dividing the size of the image seen through the microscope by the actual size of the object. In this case, the actual size of the egg is the size of the eye spot, which is 580 microns.

Therefore, the magnification is 580 microns divided by the actual size of the egg (which we don't have), resulting in a magnification value in units of times (x).
