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.
What type of microscopy does not use light?
Electron microscopy; Scanning Electron Microscopes (SEM) and Transmission Electron Microscopes (TEM). The vacuum required for electron microscopy to work correctly precludes the observation of living organisms. Biological samples must be dried then coated with a conductive metal.
Light microscopy and electron microscopy differences in practical use?
Light microscopy uses visible light to observe specimens and is suitable for studying living organisms and tissues in more detail, while electron microscopy uses a beam of electrons to provide higher resolution images of specimens at a greater magnification, making it ideal for visualizing ultrastructural details of cells and tissues. Light microscopy is better suited for routine lab work and observing larger structures, while electron microscopy is more specialized and requires specific sample preparation techniques.
What is the light that our eyes can detect known as?
The light that our eyes can detect is known as visible light.
Can bugs detect infrared light?
Yes, some bugs can detect infrared light.
What is the reason why most viruses cannot be seen by light microscopy?
Most viruses cannot be seen by light microscopy because they are much smaller than the wavelength of visible light, making them invisible to the human eye when using this type of microscope.
How is it possible to study viruses under the light microscope?
Viruses cannot be seen under a light microscope as they are too small. However, techniques like electron microscopy and immunofluorescence can be used to visualize viruses. By tagging viruses with fluorescent markers or using more powerful electron microscopes, researchers can study viruses in greater detail.

Does light microscopy offer better magnification than electron microscopy?
No
What is Dark field microscopy?
Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.
Introduction in basic techniques in microscopy?
Introduction to basic techniques in microscopy involves light microscopy, laser scanning, types of dyes, the cell, electron microscopy, differential interface microscopy, histological stains and histochemical stains.
Why couldn't you see a virus with your microscope even if you increased the eyepiece lens magnification to 100x?
Viruses are much smaller than the resolution limit of a light microscope, which is about 200 nanometers. Most viruses are around 20-400 nanometers in size, making them too small to be seen with a light microscope even at high magnifications like 100x. Specialized techniques like electron microscopy are needed to visualize viruses.

What is the status of cells used in light microscopy?
Living!
What is the Concept of Light Microscopy?

What is the differences between light reflection and light transmission microscopy?
Transmission microscopy and reflection microscopy refer to type of illumination used to view the object of interest in the microscope. Reflected light microscopy, also called episcopic illumination or just epi-illumination, uses top-down lighting to illuminate the specimen and the light is reflected back from the specimen to the viewer. This type of illumination is most often used with opaque specimens like metallurgical samples. Transmitted light microscopy, also called diascopic illumination, uses bottom-up illumination where the light is transmitted through the specimen to the viewer. This type of illumination is most often used with translucent specimens like biological cells.
