What else can I help you with?
How are we able to see cells under a microscope?
Cells can be seen under a microscope because they are transparent and the microscope uses lenses to magnify and focus light on the cells, making them visible to the human eye.
Why couldn't you see a virus with a microscope?
A virus is much smaller than the resolution limit of a light microscope, which is about 200 nanometers. Viruses typically range from 20-400 nanometers in size, making them too small to be seen with a light microscope. Detection usually requires an electron microscope, which has much higher magnification capabilities.
Why some organelle cannot be seen clearly using light microscope?
Some organelles, like ribosomes, are too small to be resolved using a light microscope because their size is close to the limit of resolution of light. Additionally, some organelles may not have distinctive features or contrast with the surrounding cytoplasm, making it difficult to visualize them clearly under a light microscope.
What is the another name for compound microscope?
The another name for a compound microscope is a light microscope, as it uses light to illuminate the specimen being observed.
Why must you use a thin specimen when viewing with a light microscope?
For a light transmission microscope, a thin sample is needed in order for the light to pass through the sample from the light source on the other side. However, you can use a dissection microscope (another type of light microscope) which illuminates the sample from above, eliminating the need for a thin sample size. As the name suggests, this is normally used in dissections, and is of low magnification.
Why can't viruses be seen with a light microscope?
Viruses are too small to be seen with a light microscope because they are smaller than the wavelength of visible light. This means that light cannot pass through them or be reflected off of them, making them invisible under a light microscope.
What year was compound light microscope invented?
The compound light microscope was invented around the late 16th century, with credit often given to the Dutch spectacle maker Zacharias Janssen as one of the early inventors. The exact year of its invention is not definitively known due to the lack of detailed records from that time period.
Why does light passes microscope?
Light passes through a microscope because microscopes use lenses to bend and focus the light that enters. This magnifies the object being viewed, making it appear larger and more detailed under the microscope. The light passes through the sample on the microscope slide, which is then magnified by the lenses to produce an image.
Can a light microscope magnfiply up to 10000?
No ten thousand is too far, given the wavelength of light, the limiting factor for optical microscopes. Perhaps a 1200 magnification is the practical limit for a simple light microscope.
What way should the mirror of a microscope face?
The mirror of a microscope should face the light source, such as a lamp or natural light. This is to ensure that the light is reflected up through the microscope stage and specimen, making the specimen easier to view under the lenses.
What does a light source do on a microscop a microscope?
A light source in a microscope provides illumination to the specimen being observed. It helps to enhance contrast and visibility of the sample, allowing for better imaging and analysis under the microscope.
A light microscope that makes the specimen appear light on a dark background is called a?
A light microscope that makes the specimen appear light on a dark background is called a darkfield microscope. Darkfield microscopy illuminates the specimen with oblique light, making it stand out against the dark background, which enhances contrast and visibility of transparent or low-contrast samples.
What came first electron microscope or light microscope?
compound light microscope - cell theory - electron microscope
How does an electron microscope differs from a light microscope?
The light microscope use the visible light; the electron microscope use an electrons beam.
What is another name for the light microscope?
Another name for the light microscope is the optical microscope.
What is a light microscope that has two more lenses?
A compound microscope
Who invent the light microscope?
The light microscope also called the optical microscope uses visibale light and a system of lenses. The actual inventor is difficult to name although Galileo's microscope was celebrated in 1624 and was the first such device to be given the name "microscope". There are claims that a Dutch spectacle-makers Hans Janssen and his son, Zacharias Janssen, but this was a declaration made by Zacharias Janssen himself during the mid 1600s.
