What is the numerical aperture of a scanning microscope?
0.1
What is a coin aperture?
slot
Numerical value for 500 689?
numerical value for 500689 numerical value for 500689 numerical value for 500689
What is another word for aperture?
hole
What is the difference between numerical and non-numerical data?
Numerical data is numbers. Non-numerical data is anything else.
What is the limit of resolution if numerical aperture of condenser is 1.25 and low power objective lense is 25?
You also need to know the wavelength :)
The high dry objective lens has a numerical aperture of 0.85 what is the limit of resolution on this microscope?
The limit resolution is (520/2.1)= 247.61 or 248
What is resolution of objective lens for 1.25 and 0.25 given wavelength of 520nm?
The formula for the resolution of an objective lens isR = (1.22(lamda))/(2*(NA))Where (lamda) is wavelength and (NA) is the numerical aperture
What is the relation between bandwidth and numerical aperture in optical communication?
when numerical aperture increases ,there will be greater lss and low bandwidth...jahi
What is the numerical aperture of a scanning microscope?
0.1
Numerical aperture 1.25 medium poser 0.25 filter 520 nm. What is the resolution. Can you distinguish two points that are 330 nm apart as being separate or will they blur into one?
Yes
Why does resolution power not depend on numerical aperture in EM?
The minimum resolvable separation distance of a light microscope depends on the wavelength of illumination and the numerical aperature. Because the electron beam has a far smaller wavelength than light used in light microscopy, it achieves far better resolution and it doesn't even involve the NE.
What is Rayleigh criterion of resolution?
According to Rayleigh Criteria, resolution is determined by the wavelength of imaging light (λ) and numerical aperture (ΝΑ) of the projection lens. Thus resolution is given by the following equation. R = k1 λ/ NA Where k1 is the process parameter describing the difficulty of the process
Does the numerical aperture of an objective depend on the focal length of the objective?
Yes.
What happens to the image when you increase magnification?
In a light microscope when magnifiaction increases resolution decreases and the object will apear blurred. It can be removed by putting immersion oil on slides or object which increase the refractive index and cause to increase the numerical aperture which ultimately cause the better resolution as resolution power depends on numerical aperture of lens. The immersion oil used can be cedar oil.
What influences resolution in regards to the compound binocular light microscope?
Resolution of a microscope is tied to the numerical aperture of the objective lens and the condenser but is influenced by other factors, such as alignment, type of specimen, wavelength of light, and contrast enhancing techniques.

Resolution of an optical microscope better with natural light rather than artificial?
The resolution of an optical microscope is not better (or worse) when using natural light. Resolution is determined by the numerical aperture (NA) of the objective.Why a vacuum in an electron microscope?The molecules that make up air would scatter the electrons in the electron beam
