Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light‚ sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection. In acoustics‚ reflection causes echoes and is used in sonar. In geology

Opportunity Rover Research Paper Review of Science Fiction Paper My science fiction paper will chronicle the Mars rover Opportunity’s time on the planet Mars from a first-person viewpoint. Opportunity will describe the destitute land of an empty planet and crippling loneliness as its twin‚ Spirit‚ gets stuck and ceases communication in 2010 [1]. Finally‚ Opportunity will reflect on the hope it has for its wellbeing as the Curiosity rover lands on Mars in 2012 [2]‚ only to realize that its mission

Trigonometry Trigonometry (from Greek trigōnon "triangle" + metron "measure"[1]) is a branch of mathematics that studies triangles and the relationships between the lengths of their sides and the angles between those sides. Trigonometry defines the trigonometric functions‚ which describe those relationships and have applicability to cyclicalphenomena‚ such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical studies.[2] It is also the

It is also used for entertainment and religious practice. • Aim: To determine the effects or contribution of the length of the string on the period for the simple pendulum and find out a

Have you ever wondered what has to happen to make the Earth quake? British engineer John Michell did. He was one of the first fathers of seismology and was also the first to correctly state what the cause of earthquakes was. In 1960‚ Michell noted that “earthquakes and the waves of energy that they make are caused by shifting masses of rock‚ miles below the surface” in a scientific memoir (USGS‚ 32). In order for you to completely understand the process of an earthquake you must first understand

recognized signs that Pinatubo was reawakening after a 500-year slumber were a series of small steam-blast explosions in early April 1991 (Hendley II‚ J.‚ Newhall‚ C. & Stauffer‚ P.‚ 2005). Scientists from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) intensified their monitoring of the volcano; they were soon joined by scientists from the U.S. Geological

Natural disasters happen all over the world‚ and they can be utterly devastating for people’s lives and the environments in which they live. Although natural disasters are caused by nature and there is nothing that we can do to prevent them happening‚ there are many different natural causes that lead to natural disasters‚ and being aware of these causes enables us to be better prepared when such disasters do arrive. One common natural disaster is flooding‚ which occurs when a river bursts its banks

Earthquakes are more newsworthy but we ignore other geological hazards at our peril. Discuss. (40marks) Geological hazards are events that are perceived as a threat to people‚ poverty and nature‚ which originate in‚ or transmitted by the physical‚ built or human environment. These can include volcanoes‚ hurricanes and earthquakes‚ which all have various effects ranging from affecting people to the natural and physical environment. Looking at earthquakes in particular‚ which are vibrations of the
