Limitations of sight can be overcome by using appropriate optical devices such as microscope‚ telescope‚ periscope and others. Limitation Of Hearing We cannot hear all the sounds around us. The range of frequency of hearing in human is from 20 Hz to 20 000 Hz. It is different according to the age of a person

Digital Multilayer disk formally known as Fluorescent multilayer disk is an optical disc format developed by D Data Inc. It is based on the 3D optical data storage technology developed for the Fluorescent Multilayer Disc by the company Constellation 3D. The change of name is due to frailer of the company called Constellation 3D due to a Swiss partner failing to provide finance to run the operation‚ later Constellation was taken over by a company called D Data Inc who reintroduced the technology under

dancer is an optical illusion‚ an optical illusion is an object causing a false visual impression. These kinds of optical illusions are always fun. What they reveal is how our brain processes visual information in order to create a visual model of the world. The visual system evolved to make certain assumptions that are almost always right (like‚ if something is smaller is it likely farther away). But these assumptions can be exploited to created a false visual construction‚ or an optical illusion

The Telescope (Reflecting) Introduction: The true beauty of the universe cannot be seen by just the naked eye‚ the telescope is controversially the most important optical instrument in history. Telescopes are widely used around the world and come in different shapes‚ sizes and go by a variety of different names. They can be used to detect noise and sound and even be used to study the stars and supernovas but are more commonly used to gain another perspective into space‚ watching planets such

The mouse brand was Onn‚ produced by Blue Trace Technology and sold by Wal-Mart. During the in-class part‚ we obtained a basic understanding of the workings of the mouse‚ but‚ to completely understand the operation of the mouse‚ we had to research the various parts individually since no blueprint for the mouse exists.

MATERIAL: CARBON FIBER Carbon Fiber is a structural material of graphite which is an allotrope of carbon. Therefore Carbon Fibre consists of carbon atoms in an atomic structure similar to Graphite. Carbon Fibre is composed of filament threads and within these threads are an accumulation of thousands of fine Carbon filaments. A filament has a diameter of approximately 5-10 micrometers. (Madehow‚ 2012) Due to the substantial stability in bonding between Graphite and Carbon Fiber the structure is
