Describe the importance of the following concepts to microscopy
What will be an ideal response?
a. magnification—The lenses of the compound light microscope project a magnified image of the specimen to a position where the eye lens can focus this image onto the retina. Magnification of this image results in a specimen detail covering a larger proportion of the retina than it would otherwise cover.
b. resolving power—Magnification is useful only when adjacent points in a specimen are seen as separate. Magnification without adequate resolving power would be "empty' in that specimen details would not be preserved.
c. contrast—Contrast is necessary to see a specimen detail against the background of the image. That is, there must be sufficient intensity or color difference, or both, between a detail and the surrounding specimen for the detail to be seen.
