However, without recognizing the privileges and locations in which an individual stands, they risk reproducing other forms of oppression such as white supremacy and patriarchy. Adopting standpoint theory is one way that scholars can ensure they are acknowledging their positions and are clear about ...
1) ray theory 光线理论 1. Using ray theory a optical sphere which can bend the incident ray through 180°is analysed and the distribution of re- fractive index is given,every ray incident on the sphere is bent through 180°. 应用光线理论分析了使入射光线偏转180度的光学介质球的工作原理,...

MICROSCOPY | Light Microscopy R.W.Lovitt,C.J.Wright, inEncyclopedia of Food Microbiology (Second Edition), 2014 Principles of Light Microscopy A basic knowledge of the theory of light microscopy is useful to understand how the general instrument works, optimization procedures, instrumentation specifica...
XRD is a scientific method of determining the precise positions or arrangements of atoms in a crystal or amorphous material where beams of X-rays strike a crystal and causes the beam of light to diffract into many specific directions.
Strictly speaking, ray optics is the limit of wave optics when the wavelength is infinitesimally small.Thus the electromagnetic theory of light (electromagnetic optics) encompasses wave optics, which, in turn, encompasses ray optics. Ray optics and wave optics provide approximate models of light ...
Well-known architects are easy to admire or dismiss from afar, but up close, oddly humanizing habits often come to light. However, while we all have our quirks, most people's humanizing habits don't give an insight into how they became one of the most notable figures in their field of ...
In theory, it would be necessary to pick each point on the object and draw a separate ray diagram to determine the location of the image of that point. That would require a lot of ray diagrams as illustrated in the diagram below. Fortunately, a shortcut exists. If the object is a ...
A ray of light from O strikes a plane mirror at an angle of 45° at point P. Since from the laws of reflection the angle of incidence i is equal to the angle of reflection r then i = r = 45°. Thus angle OPQ = 90° and the light is reflected through 90°. The ray then ...
