I was dealing with California DMV forms and no where did it tell me to send our Florida Statutes showing the towing procedures for a private property tow. They rejected my pkg. & sent letter, delaying processing 2 mths. Very frustrating to say the least.

The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object. It is the distance between two points in the object that are just resolved in the image.
NA= n x sin Where n is the refractive index of the imaging medium and is half of the angular aperture of the objective. D= /2 NA. Where is the wavelength of light used to image a specimen. D= 2 /NA2 R= 1.22 /Naomi+Second.
The primary factor in determining resolution is the objective numerical aperture, but resolution is also dependent upon the type of specimen, coherence of illumination, degree of aberration correction, and other factors such as contrast-enhancing methodology either in the optical system of the microscope or in the
The resolution of an optical microscope is defined as the shortest distance between two points on a specimen that can still be distinguished by the observer or camera system as separate entities.
The range of wavelengths for visible light is approximately 400700 nm. consequently, using the Abbé formula, it can readily be shown that the resolution limit of the light microscope is in the order of 200 nm. The 'useful' range of magnification is approximately 5001000 NA.
Since the limit of resolving power of a microscope is fixed by the structure of light, the shortest wavelength of visible light will give the maximum resolution. Among yellow, green, red and blue light color. Blue (500 nm) have the shortest wavelength so, it will give the best resolution.
In a compound microscope, the wavelength of the light waves that illuminate the specimen limits the resolution. The wavelength of visible light ranges from about 400 to 700 nanometers. The best compound microscopes cannot resolve parts of a specimen that are closer together than about 200 nanometers.
Near-ultraviolet light has the shortest usable wavelength and offers the greatest resolution. Following near-ultraviolet in descending order of wavelength are red, orange, yellow, green, blue and violet. The range in nanometers of the wavelength of the visible light is from 380 nm to 750 nm.
