Optical Fibres The Speed Of The Light
1,172 wordsThe Properties of Light Applied to Fibre Optics One of the basic properties of light is that it travels in straight lines and can have it's direction changed. This is the property which is applied to achieve the purpose of Fibre Optics which is to carry light from one place to another. The way this is done can be explained by the principle of refraction. This is the principle which governs the behaviour of light as it passes from one transparent substance to another. It states; if a ray of light...

Name Radioactivity For Becquerel's Discovery
1,178 wordsHenri Becquerel Henri Becquerel, a French physicist, was born in Paris on December 15, 1852. His grandfather, Antoine-Cesar Becquerel, had fought at the battle of Waterloo in 1815 and later earned a considerable reputation as a physicist. He made important contributions to the study of electrochemistry, meteorology, and agriculture. Henri father, Alexander-Edmond Becquerel, also made a name for himself in science. His research-included studies on photography, heat, and the conductivity of hot ga...

Incident And Emergent Rays
450 wordsPurpose: To investigate the behavior of light when it passes from air into an optically denser medium. Prediction / Hypothesis: When the light (incident ray) passes from air into an optically denser medium with an angle of incidence equal to zero, there would be no refraction. When the light passes at an angle from air into an optically denser medium, the light (incident ray) will immediately change direction and bent towards the normal which has an angle of incidence of 0 . Method: 1. The semic...

Refract Light Rays
1,355 wordsLight is a kind of electromagnetic radiation. It is made up of vibrations between a certain group of frequencies. When light is given off from a source it spreads out over a larger area. Scientists are still dumbfounded by exactly what light is. When light hits a smooth or polished surface it 'bounces' off at the same angle that it hit. Reflecting telescopes are made of concave mirrors and they have helped astronomers chart the universe because the mirrors interact with each other to magnify wha...

Focal Length Of A Lens
336 wordsLight that is emitted from a surface, or reflected from it, leaves the surface in the form of spherical wavefront's. Every point on the surface can be thought of as a source of these wavefront's. Rather than drawing the wavefront's, we customarily illustrate the propagation of light with rays. These are just lines with arrowheads that point in the direction in which the light is traveling. Lenses are objects made from a transparent material such as glass that, because of the shape of their surfa...

Nature Of Light Newton
955 wordsIsaac Newton Newton was born on the 25th December 1642 and died in 1727. He was born In Wools thorpe in Lincolnshire. His father was a farmer but he died Three months before Newton was born. His mother remarried and Newton spent his childhood with his grandmother. At school he showed great skill in making model kites, sundials and windmills. In 1665 when he was 18 he went to study mathematics at Cambridge University. He continued his studies at home when the University closed because of the plag...
