Answer #1

Total internal reflection, as the name suggests, refers to a phenomenon in which light ray after falling at an interface of two medium, gets totally reflected within the medium instead of getting refracted to another medium.

Problem Two: a. Derive or explain the condition for total internal reflection b. A beam of monochromatic light is put into a fiber optic cable. The fiber has index of refraction of 1.55 . It is surrounded by a “cladding” with index of refraction 1.36 and then an absorbing protective black layer. At what minimum angle of incidence is the light reflected back into the fiber ? c. We now have two ways to transmit digital information a distance of...

The CONDUMEX Group is the largest manufacturer of conductors, semi-conductors, and fiber optics in Latin America. Their annual revenues exceeded $200,000,000,000 and are currently positioned as a successful competitor in the global marketplace. Recently, one of the child companies of CONDUMEX, CONDUTEL (Telephone Conductors) was audited by a group of consultants. After the facilities and processes were extensively scrutinized, it was concluded that the company wastes a considerable amount of money due to product handling. The report and recommendations from...

Consider an internal combustion engine like that used in automobiles. The most common fuel used here is gasoline which is a mixture of hydrocarbons, and an octane rating is given for standardization. Therefore, we will approximate gasoline as being composed of the hydro- carbon, octane, C8H18. Another fuel that is common in racing applications is nitromethane, CH3NO2, used in top fuel dragsters. Let’s consider the combustion of each fuel with oxygen in an internal combustion engine. Let the 8-cylinder engine...

***Physical Chemistry Question***** The concept of entropy, and the second law of thermodynamics have often been used (usually misused in reality) to “explain” all kinds of things. It is frequently up to chemists to set the record straight in such cases. One argument which has been used to “disprove” evolution goes something like this: Living beings are more complex than nonliving systems. Furthermore, humans are more biologically complex than lower life forms such as monkeys. Entropy is a measure of...
