Too much light overwhelms the eye's ability to distinguish contrast and therefore detail in the specimen. Microscopes therefore have the ability to reduce the amount of light impinging on the specimen using a diaphragm, rather like the iris of the eye does.
After switching the microscope from low to high power, you may need to readjust the diaphragm to regulate the amount of light entering the lens. This adjustment helps maintain optimal image brightness and clarity at different magnifications. Start by opening the diaphragm fully and then gradually close it until the image is clear and properly illuminated at high power.
To see particles, such as individual cells or microorganisms, you would typically need a light microscope. However, to see smaller particles like viruses or nanoparticles, you would need an electron microscope.
A transparent microscope slide allows light to pass through the specimen for better image clarity and magnification. It ensures that the light source can illuminate the specimen evenly and that the microscope can capture a clear image of the sample.
A light microscope requires a light source to illuminate the specimen being observed, and lenses to magnify and focus the image. These properties allow for the visualization of small details in the specimen at a higher resolution.
Specimens for microscopy need to be thin to allow light to pass through easily, enabling clear and detailed images to be produced. Thinner specimens reduce the amount of light scattering and distortion that can occur, resulting in sharper and more accurate observations under the microscope. Additionally, thin specimens help to minimize the depth of field, allowing for better focus and clarity at various depths within the sample.

No, you need a florescent microscope to see that.

You would need an electron microscope to view HIV because it is a virus and is too small to be observed with a light microscope. Electron microscopes use a beam of electrons to create high-resolution images of tiny objects like viruses.
Magnification and resolution is in light microscope is about 500x and 0.2micro metres respectively than human eye.In e.microscope magnification is about 200,000x and resolution is 0.0005micro metres. You cannot observe live specimen through electron microscope. Lenses in light microscope are glass while e.microscope use magnetic lenses. E.microscope is relatively very larger than light microscope. You need special knowledge to handle electron microscope. You can observe through naked eye in e.microscope. A beam of electrons is sent through specimen in e.microscope.In light microscope a beam of light is sent. Electron microscope is very complex relative to light microscope.
An electron microscope would be needed to see detailed images of an internal structure of a bacterium, as it can provide much higher magnification and resolution compared to a light microscope. The electron microscope uses a beam of electrons instead of light to visualize the specimen, allowing for better visualization of internal structures at the cellular level.

We need to regulate the hunters before the animal stocks run too low.This machine will regulate the water flow into the building.
A compound microscope can either have a light bulb or a mirror. If yours has a light bulb, turn it on to view your slide. You can't use the light in your room or lab to view your slide, because you will block all that light when you use the microscope. If your microscope has a mirror then you might need a another light source to point at the mirror to view your slide.
A compound microscope can either have a light bulb or a mirror for illumination. If your microscope has a mirror, then you need sunlight or some other light source to point at the mirror to view your slide.The mirror is used to focus light up through the hole in the microscope's stage, or slide platform. The slides will contain a thin slice of material through which the light can shine, to reveal the internal structure of the sample.
