a. Scanning (small lens), red ring =
b. Low-power (medium lens), yellow ring
c. High-power (large lens), blue ring =
d. Oil immersion (largest lens), white ring =

Final answer:

The magnification abilities of microscope objective lenses vary, with scanning typically at 4x, low-power at 10x, high-power at 40x, and oil immersion at 100x. When coupled with a standard 10x eyepiece, total magnifications of 40x, 100x, 400x, and 1000x are achieved, respectively.

Step-by-step explanation:

The magnification abilities of the objective lenses on a microscope are integral for viewing specimens at various levels of detail. These individual magnification levels can be calculated by multiplying the magnification of the objective lens by that of the eyepiece. For instance:

  • A scanning objective lens, often identified with a red ring, typically has a magnification of 4x.
  • The low-power objective lens, marked with a yellow ring, commonly magnifies by 10x.
  • A high-power objective lens with a blue ring usually offers 40x magnification.
  • The oil immersion objective lens, which may have a white ring, provides the highest magnification at 100x.

When these are used with a typical 10x eyepiece, the total magnification can be calculated: Scanning (4x objective) * (10x eyepiece) = 40x total magnification, low-power (10x objective) * (10x eyepiece) = 100x total magnification, high-power (40x objective) * (10x eyepiece) = 400x total magnification, oil immersion (100x objective) * (10x eyepiece) = 1000x total magnification.
