The light is necessary when you are using a microscope because if you don't have the light turned on, then the object or specimen you would like to examine won't be showing up. The light makes you have the capabiltiy to see what your object looks like under the microscope, and if your light isn't being used, then you will not see your object, probably only darkness!!! (Hope this helped)
Oil is necessary when using the 100x objective in a microscope to increase the resolution and clarity of the image. The oil has a similar refractive index to glass, reducing light refraction and increasing the numerical aperture, allowing for better resolution at high magnifications.
Opaque objects do not let light pass through them, so they block the light needed for the microscope to form an image. This prevents the microscope from capturing a clear image of the object. As a result, opaque objects appear dark and featureless when viewed under a light microscope.
To improve the resolution of a microscope, you can use a lens with a higher numerical aperture, reduce the wavelength of light used for imaging (such as using blue light instead of red light), and ensure that the microscope is properly focused and aligned. Additionally, using immersion oil between the lens and the specimen can also enhance resolution.
You can adjust the amount of light that passes through the specimen on a compound microscope by adjusting the condenser. Lowering the condenser increases the amount of light, while raising it decreases the intensity of the light. Additionally, you can also adjust the light intensity using the light source controls on the microscope.
The light source on a microscope, typically a bulb or LED, provides the necessary illumination to view materials on a glass slide. This light passes through the specimen on the slide, allowing it to be magnified and observed through the microscope's lenses. The intensity and angle of the light can be adjusted to optimize visibility and contrast.
light microscope is the simplest, in manufacturing and using
The density of the nucleus can be seen using the light microscope, because the light microscope enlarges or makes the nucleus bigger.
None can. They have to be seen using a electron microscope.
light is must for optical microscope while is not necessary for nonn optical one
you...
ribosomes are not seen by using a light microscope bcz of its small size
Using an electron microscope allows you to identify structures within the nucleus, such as nuclear pores, nuclear lamina, and nucleoli, which are not visible under a light microscope due to their smaller size and lack of contrast in light microscopy. Additionally, electron microscopy can reveal fine details of chromatin organization and nuclear envelope structure that are not easily resolved with a light microscope.
Optical, though to see smaller organelles and structures in higher resolution an electron microscope may be necessary.
The basic requirement for you to see an object using the microscope is light. The amount of light will determine the visibility of the specimen.
You can't change the contrast on the microscope, that would have to be done using dyes.
Things that are too small for a light microscope, such as viruses and molecules, can be viewed using an electron microscope. Electron microscopes use a beam of electrons instead of light to magnify objects at a much higher resolution than light microscopes.
it has light limited magnification
