8th physics light reflection refraction eyes defect and dispersion The ray of light which falls on the mirror surface is called incident ray. The point at which the incident ray strikes the mirror is called the point of incidence. The ray of light which is sent back by the mirror is called the reflected ray. The ‘normal’ is a line drawn at right angles to the mirror surface at the point of incidence. The angle between incident ray and normal is called the angle of incidence. The angle between

Fences by August Wilson is a drama filled play surrounding a man named Troy. Throughout this play many things occur such as adultery‚ a boy leaving his home to become a man‚ and many relationships being torn apart. In this particular play there were many symbolic and ironic situations that took place. Since Troy had an unhealthy relationship with his father‚ it affected the way he raised his children. In this play father and son relationships are damaged. Troy‚ the protagonist‚ is an African American

3. Recent technological developments have allowed greater use of the electromagnetic spectrum 1. describe electromagnetic waves in terms of their speed in space and their lack of requirement of a medium for propagation In space (a vacuum) electromagnetic waves travel at the speed of light‚ a constant equal to 3.00108ms1. Unlike sound waves‚ electromagnetic waves do not vibrate particles‚ therefore they do not need a medium (substance) to propagate (move). 2. identify the electromagnetic wavebands

GRAVITATION Kepler’s Laws Towards the end of the sixteenth century‚ Tycho Brahe collected a huge amount of data giving precise measurements of the position of planets. Johannes Kepler‚ after a detailed analysis of the measurements announced three laws in 1619. 1. The orbit of each planet is an ellipse which has the Sun at one of its foci. 2. Each planet moves in such a way that the (imaginary) line joining it to the Sun sweeps out equal areas in equal times. 3. The squares of the periods

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches
