EVERYDAY SCIENCE

Detailed explanation-1: -A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.

Detailed explanation-2: -Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.

Detailed explanation-3: -Magnification is how much an image is enlarged under a microscope. Resolution is the amount of detail you can see in an image. You can enlarge a photograph indefinitely using more powerful lenses, but the image will blur together and be unreadable.

Detailed explanation-4: -Therefore, scientists must use microscopes to study cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes.

Detailed explanation-5: -In a compound microscope, the object being viewed is magnified twice: First, the objective lens makes the object appear 5, 10, 40, or even 100 times larger, and then the eyepiece lens magnifies that image an additional 10 times.
