Because in light microscpoe is used to see living cell but in electron you only get dead cell the another functions of light microscope is It's relatively cheap it till you see used with out its electricity but it can be used by sunlight when we see the electron microscope Costas High or the maintenance also High and this specious must be dried but in the light microscope you can use the specious not dried

Introduction:
Microscopes are essential tools used in scientific research to study small objects or organisms that cannot be seen with the naked eye. There are two main types of microscopes: light microscopes and electron microscopes. Both have their advantages and limitations, and they work on different principles.

Light Microscope:
Light microscopes, also known as optical microscopes, use visible light to illuminate the specimen and produce an image. They are commonly used in biology and medicine for routine laboratory work. The key features of light microscopes are:

1. Principle: Light microscopes rely on the interaction between light waves and the specimen. The light passes through the objective lens, interacts with the specimen, and then magnifies the image formed.

2. Magnification: Light microscopes can achieve magnifications up to 1000x, allowing researchers to see objects as small as a few micrometers.

3. Resolution: The resolution of a light microscope is limited by the wavelength of visible light, which is around 400-700 nanometers. This means that it can distinguish structures that are at least 200-350 nanometers apart.

4. Sample Preparation: Specimens for light microscopy are usually thin and transparent. They may require staining or fixing to enhance contrast and visualize specific structures.

Electron Microscope:
Electron microscopes use a beam of electrons instead of light to magnify and visualize specimens. They provide much higher magnification and resolution than light microscopes. The key features of electron microscopes are:

1. Principle: Electron microscopes use a beam of electrons instead of light. The electrons are focused using magnetic lenses and interact with the specimen to produce an image.

2. Magnification: Electron microscopes can achieve magnifications up to 1,000,000x, allowing researchers to see objects as small as a few nanometers.

3. Resolution: The resolution of an electron microscope is much higher than that of a light microscope. It is limited by the wavelength of electrons, which is about 0.005 nanometers. This allows electron microscopes to distinguish structures that are only a few nanometers apart.

4. Sample Preparation: Specimens for electron microscopy require extensive preparation. They must be dehydrated, embedded in resin, and sliced into ultra-thin sections. In some cases, they may also need to be coated with a thin layer of metal.

Differences:
The main differences between light microscopes and electron microscopes are:

1. Principle: Light microscopes use visible light, while electron microscopes use a beam of electrons.
2. Magnification: Electron microscopes can achieve much higher magnifications than light microscopes.
3. Resolution: Electron microscopes have much higher resolution than light microscopes.
4. Sample Preparation: Electron microscopy requires more complex and time-consuming sample preparation compared to light microscopy.
5. Cost: Electron microscopes are significantly more expensive than light microscopes.
6. Applications: Light microscopes are commonly used in biology and medicine, while electron microscopes are used in materials science, nanotechnology
