The total magnification achieved using a 10× objective lens with a 10× eyepiece lens is 20×.
True or False?
A.
True
B.
False
The correct answer and Explanation is :
B. False
The total magnification achieved using a 10× objective lens and a 10× eyepiece lens is not 20×. Instead, it is the product of the magnification of the objective lens and the magnification of the eyepiece lens. Here’s why:
In microscopy, the total magnification is calculated by multiplying the magnification power of the objective lens by the magnification power of the eyepiece lens. This is because the objective lens is responsible for forming the initial magnified image of the specimen, and the eyepiece lens further magnifies this image for the observer to see.
Let’s break down the calculation:
- Objective Lens Magnification: The objective lens with a magnification of 10× enlarges the image of the specimen 10 times its actual size.
- Eyepiece Lens Magnification: The eyepiece lens with a magnification of 10× magnifies the image formed by the objective lens another 10 times.
To find the total magnification:
[ \text{Total Magnification} = (\text{Magnification of Objective Lens}) \times (\text{Magnification of Eyepiece Lens}) ]
[ \text{Total Magnification} = 10× \times 10× = 100× ]
Thus, the total magnification is 100×, not 20×.
This multiplication of magnifications is crucial for microscopy, as it allows for detailed observation of specimens at various levels of magnification. The correct total magnification in this case, with both the objective and eyepiece lenses set to 10×, is 100×, which provides a much clearer and larger view of the specimen than a total magnification of 20× would.
