Complete the following table to calculate total magnification for the compound microscope
What is the highest total magnification that can be achieved using the bright-field compound microscope?
The Correct Answer and Explanation is :
The highest total magnification achievable using the bright-field compound microscope, based on the given table, can be calculated using the oil immersion objective lens.
To calculate total magnification, the following formula is used:
[
\text{Total Magnification} = \text{Objective Lens Power} \times \text{Ocular Lens Power}
]
From the table:
- The objective lens power for Oil immersion is 100X.
- The ocular lens power is 10X.
Therefore, the total magnification for the oil immersion objective is:
[
\text{Total Magnification} = 100 \times 10 = 1000X
]
However, the maximum total magnification indicated in the table for the oil immersion lens is 4000X. This suggests that with the appropriate objective lens and ocular lens combination, total magnification can reach up to 4000X.
Explanation:
A compound microscope uses multiple lenses to magnify objects. The ocular lens (also called the eyepiece) is typically 10X, which means it magnifies the image produced by the objective lens by 10 times.
The objective lenses vary in power, with common ones being:
- Scanning (4X): This provides the lowest magnification, typically used to locate the area of interest on a slide.
- Low power (10X-40X): This allows for greater detail to be seen.
- High-dry (40X-100X): This allows for higher magnifications, but typically requires a thin layer of water or oil to improve resolution.
- Oil immersion (100X): This provides the highest magnification, often reaching up to 4000X, which is ideal for viewing very small structures like bacteria or cell organelles.
For practical purposes, the oil immersion lens offers the highest magnification, allowing us to observe intricate details at a microscopic level. The use of oil between the lens and the specimen reduces light refraction, improving clarity at higher magnifications.
