Why cant you something one centimeter long with the microscope?
You omitted part of the question.
It might help if u fix your question
To understand why you can't see something one centimeter long with a microscope, we need to consider the principles of microscopy and the limitations it has.
Microscopes are instruments that use lenses to magnify objects, allowing us to see tiny details that are not visible to the naked eye. The resolution of a microscope determines its ability to distinguish two adjacent points as separate entities. The resolution of a light microscope is limited by the wavelength of the light used.
The resolution of a light microscope is around 200 nanometers, which means it can distinguish between two points that are at least 200 nanometers apart. One centimeter is equal to 10,000,000 nanometers, which is far beyond the resolving power of a light microscope. Therefore, objects that are one centimeter long cannot be clearly visualized using a light microscope.
To study objects or structures of that size, different tools or techniques are required. For example, you might use a macroscopic imaging device, such as a macro lens on a camera, to capture images of objects on that scale.
In summary, the limited resolution of a light microscope prevents us from seeing objects one centimeter long. For larger objects, other imaging techniques or tools are more suitable.
