PURPOSE: APPARATUS: Fiber optics of various lengths Trainer boards Function generator and LED Circuits Radio Wood board and tape Reflective Material Paper Ac voltmeter Cables INTRODUCTION: Fiber optics refers to a field of study under both engineering and applied sciences. It deals with the designing and usage of optical fibers. The fibers are flexible and transparent manufactured through the drawing of plastic or silica (glass) to diameters slightly greater than those of human hairs. Most often, optical fibers serve in the transmission of light between the two fiber’s ends. They find a wide use communications since they can ...

Discovery of ultraviolet light

Ultraviolet radiation is very significant in the tanning individual who are interested in making their skin look like leather as well as for vampires killing, yet it cannot be seen or else felt.

Solving Social Problems: Solar Energy in Rural India

The developing world grapples with the lack of access to electricity. Third world countries have poor electrical infrastructure which is still in the nascent stages of development. As a result, majority of people, especially those living in rural areas, have no access to electricity. The reach of the electrical grid in countries is limited to towns, and the poor who have access to electrical power supply suffer frequent and prolonged power blackouts. As a result, people in such countries result to unclean and unhealthy means of lighting, such as kerosene and diesel generators. The kerosene lamps cause respiratory problems ...
