Refraction and Snell’s Law When an ultrasonic wave passes through an interface between two materials at an oblique angle‚ and the materials have different indices of refraction‚ both reflected and refracted waves are produced. This also occurs with light‚ which is why objects seen across an interface appear to be shifted relative to where they really are. For example‚ if you look straight down at an object at the bottom of a glass of water‚ it looks closer than it really is. A good way

after every eighth element. Lothar Meyer and Demetriv Mendeleev published their own periodic table. Mendeleev arranged the elements in order of increasing atomic weight and grouped the elements of similar properties together. William Ramsay and Lord Rayleigh discovered the noble gases‚ which were added to the periodic table as group 0. Ernest Rutherford showed that the nuclear charge was proportional to the atomic weight of the element. Glen Seaborg found the transuraniun elements and rearranged the

The development of Periodic Table Elements such as gold and silver have been known since the earliest times. In 1649‚ a German alchemist‚ Hennig Brand made the first scientific discovery of an element‚ phosphorous. In the next 200 years‚ knowledge about the properties of elements and their compounds was gained. By 1869‚ 63 elements had been discovered in total. Scientists began to categorise those elements according to the similarities of their physical and chemical properties‚ which become the

This phenomenon was first reported in 2009. Two papers have been published on arXiv.com‚ the first describing the phenomenon (Shiryaeva et al)‚ the second offering a theoretical model for the observations (Amjadi et al). The

To examine the effects of different factors‚ such as Prandtl‚ Reynolds and Rayleigh numbers on heat transfer in a square enclosure‚ the laminar flow of Newtonian fluids was approximated and then laminar flow of non-Newtonian fluids‚ such as carboxy methyl cellulose (CMC) and carboxy poly methylene (Carbopol) water solutions were
