What is an Abbe number?
An Abbe number is a number which represents the reciprocal of the dispersive power of a substance with transparent qualities.
What happens if the ruled surface of the grating faces the collimator?
Lines will be formed at the opposite side of the observer if the ruled surface of grating faces the collimator due to reflection
What is another name for grids?
Grating, Mesh, Lattice, framework, Network.
A diffraction grating produces a first-order maximum at an angle of 20.0 degrees what is the angle of the second order maximum?
65.6
What word means the same thing as lattice?
fretwork, grating, grid, grille, latticework, mesh, network, openwork, reticulation, tracery, trellis, web,
What is the difference between dispersive and resolving power of diffraction grating?
The ability of an optical instrument expressed in numerical measure to resolve the image of two nearby points is termed as resolving power. The dispersive power of a diffraction grating is defined as the rate of change of the angle of diffraction with the wavelength of lite. S M SOHEL RANA IU
What is dispersive power of a grating?
Dispersive power is defined as the rate of change of angle of diffraction with the change of wavelength in a particular order of spectrum. Type your answer here...
How diffraction grating could be used as the dispersive element?
Diffraction grating could be used as the dispersive element because of the ability of light to be broken according to various wavelength.
What is meant by dispersive power of prism?
the dispersive power of prism can be defined as the rate of change of angle of deviation in specific spectrum of light ..
What is dispersive power of a prism?
.04 to .05 typically about 0.47
Why must the slit width of a prism monochromator be varied to provide constant effective bandwidths but a nearly constant slit width provides cnstant bandwidth with a grating monochromator?
Prisms and gratings have different dispersive properties. Grating has a linear dispersion of wavelengths meaning the band on the focal plane varies linearly with the wavelength. Prisms are not linear, the shorter the wavelength the greater the dispersion. Thus, when a spectrum is being scanned, the dispersive device needs to rotates different amounts depending on whether it is prism or grating to focus light on the exit slit. If its grating, the slit width will need to be varied minimally; if it is a prism, the slit width will need larger changes as the dispersion gets greater.
Can you use a sodium lamp for finding dispersive power of prism?
yes of-course
What is the principle of dispersive power of prism?
It works under the principle of refraction and the phenomenon of dispersion.
What is the resolving power of a scanning electron microscope?
the resolving power of light microscope is 0.2 micrometr
Explain the relationship between the resolving power of the microscope and the wavelength of the light being used?
Resolving power of microscope is inversely related to the wavelength of the light used. So shorter the wavelength, greater the resolving power.
What is horizontal resolution?
resolving power
What is the difference between the resolving power and the magnifying power?
