Light and Optics What is Light? Light is a component of the electromagnetic spectrum, which in turn is a collection of waves. These waves include Microwaves, X-Rays, radio waves, Gamma Rays, and visible light. Near the end of the 17th century, concerns regarding whether light is composed of waves or particles surfaced (“Theory of Light”)…

Newton’s Particle Theory Newton’s particle theory of light is also known as the Corpuscular Theory of Light. Newton published Opticks in the year 1704, 17 years after the publishing of Principia (“Newton’s Particle Theory”). In Opticks, Newton said that light is made up of little masses, which implies that a horizontal light beam near the earth forms a parabola, thus undergoing a projectile motion. The immensity of the speed of particles of which light is composed is the reason why it is observed as a straight line in spite of its projectile motion. The speed of the travelling of light is 300m per microsecond, during which “it should fall a distance y = 1/2gt2 = 5*10-12 m, much too small to be seen” (“Newton’s Particle Theory”). The particle model easily explained a range of the then known properties of light. For instance, it explained why the angle of incidence and the angle of reflection of light were equal as light reflected from a smooth surface. This also explained the phenomenon of bouncing back of a frictionless elastic ball from a smooth surface. Refraction is a major property of the particle theory of light. ...
on of wave was in parallel direction to the wave travel’s direction rather than perpendicular to the wave travel direction as happens in the case of light. Although the Corpuscular Theory of Light could explain the phenomena of primary and secondary rainbows, yet it failed to lay down an appropriate explanation of the supernumerary bow, the iridescent cloud, or the corona. The Wave Theory of Light Huygens proposed a successful theory of the wave motion of light in three dimensions. In this theory, Huygens said that light wave emerges from surfaces like onion’s layers. Light waves are spherical in uniform mediums or vacuum. As the wave surfaces propagate with the speed of light, they spread out. According to Huygens, gravity does not affect the light waves. Huygens disagreed with Newton saying that the speed of light reduces as it travels from air to water whereas it increases when it moves from water to air. Later, Huygens was found to be correct. Each color exhibited by the wave as it spreads out from the source carries a different wavelength. Supernumerary bows could be explained with the assumption of light as a wave. Huygens wave theory elaborates the reason why light spreads out of a slit or a pin hole instead of making a straight line. Although the theory of Newton preceded Huygens’s, yet early experiments were explained better by the theory of Huygens. Huygens’s principle can be used to assess the location of a certain wavefront in the future if its present location is known. The Dual Nature of Light In the year 1803, Thomas Young shone light through a screen to study the interference of light waves. The screen had two equally separated slits. As light passed through them, it emerged spreading out following the Huygen’s principle. The two wave fronts ...Download file to see next pagesRead More

Removal of Pedestrian Crossing Traffic Lights
They are usually installed to enable the crossers to cross the road without any hindrance but these traffic lights create a hindrance for the traffic flow as due to pedestrian crossing traffic lights, the vehicles are required to break their speed and assemble at the signal for allowing the pedestrians to cross the road.

Fibre Optics
Basically, fiber optics refer to the cables or lines which contain optically pure glass used to transmit digital information signals. The bedrock of these cables is formed by this optically pure glass which is more or less as thin as a human hair but has astounding ability to carry digital information over far across corners of the world.

Fibre optics
In this theory the light is used in the approximation of the light acceptance and also as a guideline property to optical fiber (Hecht 1999, pg. 12). The next theory describes light as being an electromagnetic wave which is known as mode theory or the wave representation approach.

Fibre Optics
Fibre optics however is being utilized since more than a hundred years. Optical fibre is a model that has evolved greatly over time. From guided transmission lights experiments to lasers and light emitting diodes (LED), and to dense wavelength-division multiplexing (DWDM), the area under which optical fibre can be used has expanded.

Optics Study Report
Several theoretical and experimental studies have been undertaken to investigate the feedback systems or random lasers, using semi-conductor powder and other organic materials (Marouf and Zekri, 1661). The difference between the conventional laser and the random laser has been identified in their feedback mechanisms, where the conventional laser applies a system of gain medium and cavity to give a feedback.

Earhtquake lights
It was when Japanese Seismologist collected 1,500 reports of luminescent phenomenon from various Japanese tremors particularly Japan's Idu Peninsula earthquake in November of 1930 and were able to draw substantial conclusions. However, the scientific community remained skeptical until several unusual earthquakes generated a number of earthquake lights (EQL) in Matashiro Japan in the 1960s.
