Based on the bar graph, sales of Bracelets are represented by the red bar. This is the common way numerical aperture is defined for optical fibers. It is unity in air. Numerical Aperture. The quantity has no unit. An optical fiber with ‘high’ numerical aperture will confine light more strongly in the core, and so support guidance further above cut-off. © 1942 American Microscopical Society In the indirect ratios you will always be given ratios so you can use them to calculate or convert the currency or any other unit. Example of a number series test question – line number series. Not bad! Numerical Aperture can also be defined in terms of the index of refraction of the fiber core and cladding. Following Snell’s law, the maximum acceptance angle can be determined: Where:nf  is the index of refraction of the fiber core, nc is the index of refraction of the cladding,θc  is the critical angle for total internal reflection, andθa  is the maximum 1/2 acceptance angle.

This material is typically air, making it equal to approximately 1.0, as shown in the figure below. While most candidates will receive an invite to take a numerical reasoning test, the style of test questions is likely to be very different. Answer: a The refractive index of air is unity. The numerical aperture of a microscope objective is the measure of its ability to gather light and to resolve fine specimen detail while working at a fixed object (or specimen) distance.
