Refractive index measurements of a prism at grazing emergence
(Universiti Malaysia Perlis, 2011)
A new method is reported to find the refractive index (n) of prism materials by measuring only the angle of incidence (i) when the emergent ray grazes the surface at which refraction takes place. A new general equation is ...
The influence of aluminium doping and oxygenation on the porperties of YBa₂Cu₃-ₓAlₓO₆.₅+δ (0≤x≥0.045) HTSC
(Universiti Malaysia Perlis, 2013)
The effect of Al₂O₃ particle addition on the crystal structure and superconducting properties of YBa₂Cu₃O₆.₅+δ (YBCO) ceramics is systematically studies. Samples were synthesized using a solid reaction to prepare YBa₂Cu₃O7-δ ...
The response of a window glass to the frequencies of sound
(Universiti Malaysia Perlis, 2013)
There are a several methods for detecting sound inside a building. In research a method of a bean splitter is used for detecting sound and therefore reflectance and transmittance of windows to the sound have been studied. ...
