What would be the magnification of a telescope with a focal length of 3000 millimeters using an eyepiece of focal length equal to 15 mm?
200 would.
What factors determine the limit of resolution of a light microscope?
The limit of resolving power of a microscope is described by the Abbe criterion: d=wl/NA d being the minimal resolvable distance between two spots of the object wl being the wavelength of the light used NA being the numerical aperture of the microscope, which is equal to n*sin(a) with n being the refraction index of the immersion liquid between object and objective a being the aperture angle because sin(a) is always smaller than 1 and n cannot rise above 1.7, the maximal resolving power of a microscope is about d=wl/2 and thus only depends on the wavelength of the light used, which normally will be about 600 nm.
How is the image projected through a telescope?
The main lens or mirror produces a virtual image of the obect being looked at, and it occurs at a distance behind the lens (or in front of the mirror) equal to the focal length. The telescope also has an eyepiece whose function is to allow the oberver to see the virtual image. Many telescopes come with a range of different eyepieces that give different amounts of magnification.
Where did Galileo invent the telescope?
Galileo didn't actually invent the telescope, though he was one of the first to use it for astronomical observations. At the time he constructed his first telescopes, he was teaching at the University of Padua in Italy.
Is an atom microscopic?
No. Atoms are submicroscopic, meaning they are too small to be seen even with a microscope.
If a light microscope has an eyepiece lens of magnification x15 what magnification of objective lens would be needed to get a total magnification of x1500?
The total magnification is equal to the magnification of the eyepiece multiplied by the magnification of the objective lens. So in this case the objective lens would need to be 100X.
What does 1 ocular micrometer division equal on a 10x objective?
1 ocular micrometer scale is equal to 1micrometer when it is seen from 10X objective it will be magnify by 100 times so, 1 ocular micrometer division become 0.1mm ( 1um * 100 = 0.1mm)
What is the magnificatio of atelescope if the focal lenghts of objective and its eyepiece are 200cetimeter?
If the focal lengths of the objective and eyepiece are equal,then the magnification is ' 1 '.
How does 4x on the low power equal 40 x on the microscope?
The objective lens (right above the slide stage) is 4x. The eyepiece (what you look into) is 10x. 4 times 10 = 40. Whatever the objective lens power is, you have to multiply it by the eyepiece power (usually 10x) to get the overall magnification.
What is parfocal capability?
lenses: set up or arranged so that when one lens is changed for another, there is no change in focus. * Applied usually to turret mounted lenses e.g. on microscope; also in telescopes: ~ eyepieces: changing one for another does not require refocusing. * When the distance from the object to the rear principal plane of each lens is equal, they are said to be parfocal.

What would be the magnification of a telescope with a focal length of 3000 millimeters using an eyepiece of focal length equal to 15 mm?
200 would.
If thirteen ocular divisions line up with two division of the stage micrometer what is the diameter of a cell that spans sixteen ocular divisions?
Two divisions of the stage micrometer is equal to 20 micrometers. 20 micrometers/13 = 1.54micrometers You multiply this by 16 to find the diameter of the cell. 1.54 x 16 = 24.62 micrometers
Objective of life?
To prepare for "The Life"Answer Each one of us has different objective in life. All we have to do is to know and follow the most important rule in this planet. This rule says "Every being has an equal right to live here, to develop here and to carry out his tasks here". Its' up to you on how to deal your own objective.
Why does series rlc circuit provides voltage magnification at resonance?
IN A SERIES RLC CIRCUIT XL=XC.THEREFORE, IMPEDANCE Z IS MINIMUM AND Z=R.SINCE THE IMPEDANCE IS MINIMUM,CURRENT IN THE CIRCUIT WILL BE MAXIMUM. XL=XC MULTIPLYING BY MAX. CURRENT Io (AT RESONANCE) ON BOTH SIDES, WE GET, IoXL=IoXC I.E. Vlo=Vlc(POTENTIAL DIFFERENCE ACROSS INDUCTANCE IS EQUAL TO THE POTENTIAL DIFFERENCE ACROSS CAPACITANCE AND BEING EQUAL AND OPPOSITE THEY CANCEL EACH OTHER.)SINCE Io IS MAXIMUM,Vlo AND Vco WILL ALSO BE MAXIMUM.THUS,VOLTAGE MAGNIFICATION TAKES PLACE DURING RESONANCE.HENCE,IT IS ALSO REFERRED TO AS VOLTAGE MAGNIFICATION CIRCUIT.
