Oil is used in microscopy because air Can't bend light enough. It's hard to explain in words, but, you know how when you put a stick in water, it appears bent? well in simple terms, oil bends it more, and the information (image information) increaces. It's kind of like having a bigger telescope, the oil increases the apature of the lens you are using, it gathers more information for the eyepiece to magnify, therefore you see more. If you want a detailed explination, please post again.

What mirror is used for oil immersion?
A high-quality microscope objective lens with a specialized coating is typically used for oil immersion microscopy. The lens is designed to work with a specific type of oil (usually immersion oil) to enhance resolution and numerical aperture by reducing light loss due to refraction. Oil immersion microscopy is commonly used for high-magnification studies requiring precise imaging, such as in medical or biological research.
What is the recommended type of immersion oil to use for microscopy?
The recommended type of immersion oil to use for microscopy is colorless, odorless, and has a refractive index closely matching that of glass, typically with a refractive index of 1.515.
Why is cedar wood used with oil immersion objective?
Cedar wood is used with oil immersion objectives in microscopy because it has a refractive index similar to that of the oil (usually 1.515) used to fill the space between the objective lens and the specimen. This minimizes light scattering and improves image quality by increasing numerical aperture and resolving power.
What is OIO in microscope?
oIO, stands for oil immersion objective. it was discovered during 1870. the OIO, magnifies the actual size of the specimen , 100 times, with the aid of placing a drop of ceddar oil at the top of the coverslip in slide. Remember that the OIO objective must touch the surface of the oil.
What is the definition of the term fluorescence microscopy?
Fluorescence microscopy is a technique used to visualize biological structures or molecules by inducing fluorescence in the sample and detecting the emitted light using specialized microscopes. This technique is commonly used in cell biology to study the localization and interaction of specific molecules within cells.

Can mineral oil be used place of immersion oil?
Mineral oil can be used as a substitute for immersion oil in some cases, as both provide similar refractive indices that can enhance the clarity of microscopic images. However, immersion oil is specifically formulated for microscopy, offering better optical properties and reducing the risk of damage to the microscope lens. Using mineral oil may not provide the same level of performance and could potentially lead to issues with lens clarity or longevity. It's best to use immersion oil designed for microscopy whenever possible.
Why does oil immersion improve resolution in microscopy?
Oil immersion improves resolution in microscopy by reducing the refraction of light as it passes through the specimen. This helps to minimize the scattering of light and allows for clearer and more detailed images to be produced.

What is the status of cells used in light microscopy?
Living!
Which type of microscopy is used for colorless specimens?
Phase contrast microscopy is often used for viewing colorless specimens, as it enhances the contrast between different parts of the specimen based on density differences. This type of microscopy is particularly useful for observing live biological samples without the need for staining.

What are the differences between two-photon microscopy and confocal microscopy in terms of their imaging capabilities and applications?
Two-photon microscopy and confocal microscopy are both advanced imaging techniques used in biological research. Two-photon microscopy allows for deeper imaging into tissues compared to confocal microscopy, making it ideal for studying thick samples. Additionally, two-photon microscopy is less damaging to living samples due to its longer wavelength light. On the other hand, confocal microscopy provides higher resolution images and is better suited for imaging thin samples. Confocal microscopy is commonly used for studying cell structures and dynamics at a cellular level. In summary, two-photon microscopy is better for deep tissue imaging, while confocal microscopy is preferred for high-resolution imaging of thin samples.
