Question

multiple choice question
which microscope lens gives the greatest magnification?

ocular lens
10× objective lens
oil immersion lens
40× objective lens

Explanation:

To determine which microscope lens gives the greatest magnification, we analyze each option:

• Ocular lens (eyepiece) typically has a magnification of around 10× (varies, but generally lower than many objective lenses for high - power viewing).
• 10× objective lens has a magnification of 10×, which is relatively low for objective lenses.
• Oil immersion lens typically has a magnification of 100×. This is because the use of immersion oil (which has a refractive index similar to glass) helps to minimize light refraction at the lens - specimen interface, allowing for much higher magnification compared to dry objective lenses.
• 40× objective lens has a magnification of 40×, which is less than the 100× of the oil immersion lens.

Answer:

C. oil immersion lens
