How do you find the actual size of a specimen?
Similarly, how does magnification affect the actual size of the specimen?
The magnification is a measure of how much bigger an image appears than the actual size of the specimen. If the objective lens has a magnification of x40 and the eyepiece lens x10, the overall magnification would be x400. But size isn't everything – the level of detail that you can see is called the resolution.
Also Know, why is it important to start at a lower magnification and then increase? When using a light microscope it's important to start with the low power objective lens as the field of view will be wider, increasing the number of cells you are able to see. Extra care is needed here because the high-powered lens can become damaged as it's very close to the slide.
Keeping this in view, how do you find the specimen under a microscope?
Scan the slide (right to left and top to bottom) at low power to get an overview of the specimen. Then center the part of the specimen you want to view at higher power. Rotate the nosepiece to the 10x objective for 100x magnification. Refocus and view your specimen carefully.
How do you calculate the magnification of a leaf?
To calculate the magnification, simply multiply the ocular lens (10x) by the objective lens. With this microscope you can obtain four different magnifications: 40x, 100x, 400x and 1000x.
