The Microscope And Cells

Explanation
Magnification refers to the process of making something appear larger than its actual size. It does not involve any physical enlargement of the object itself. This can be achieved through the use of lenses or other optical devices that make the object appear closer or more detailed. Magnification is commonly used in microscopy, photography, and binoculars, where it allows for a closer and more detailed view of objects that are otherwise too small to see clearly.

Explanation
The handle is not a part of a microscope. A microscope typically consists of an objective lens, stage, and mirror. The objective lens is responsible for magnifying the specimen, the stage holds the specimen in place, and the mirror reflects light to illuminate the specimen. The handle, on the other hand, is not essential to the functioning of a microscope and is not typically found on all microscope models.

Explanation
The objective lens is the lens on the microscope that is changed when the magnification is adjusted. This lens is responsible for gathering light and magnifying the specimen, allowing for a detailed view. By adjusting the objective lens, the magnification can be increased or decreased, providing different levels of detail and clarity in the image.

Explanation
When using a microscope, it is important to hold it by the base. The base is the bottom part of the microscope that provides stability and support. By holding the microscope from the base, you ensure that it remains steady and does not tip over or fall. This is especially important when adjusting the focus or moving the microscope around. Holding the microscope by the base also helps to prevent any accidental damage to the delicate parts of the microscope, such as the eyepiece lens or the stage.

Explanation
The magnification of a microscope is calculated by multiplying the magnification of the eyepiece by the magnification of the objective lens. In this case, the eyepiece has a magnification of x10 and the objective lens has a magnification of x20 for option a and x40 for option b. Therefore, the magnification for option a is 10 x 20 = 200 and the magnification for option b is 10 x 40 = 400.
