research on radio waves‚ to us‚ radio waves were just waves going through the atmosphere‚ carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves‚ and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves‚ which represent voice and other sounds and radio frequency

Radio Waves In the modern society‚ radio is the most widely used medium of broadcasting and electronic communication : it plays a major role in many areas such as public safety‚ industrial manufacturing‚ processing‚ agriculture‚ transportation‚ entertainment‚ national defense‚ space travel‚ overseas communication‚ news reporting and weather forecasting. In radio broadcasts‚ they use the radio waves which can be both microwaves and longer radio waves. These are transmitted in two ways: amplitude

Beginning in the summer of 1869 Gustave Courbet produced a series of paintings depicting stormy seas during his stay at Etretat on the Normandy coast. The Wave (La Vague c.1872) exhibited in the National Gallery of Victoria is one such painting that features the central motif of a cresting wave. While many viewed the work as a simple realist seascape‚ the political implication of the work suggested by some of Courbet’s contemporaries is hardly discernable to the modern viewer. It can only be understood

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

Electromagnetic waves are radiated energy of all different strengths. They’re different from sound waves and water waves because they have the ability to travel through empty space. A vacuum. These are the only types of waves that do not need any type of medium because of photons. Photons are tiny particles that don’t get traveled through‚ but make up electromagnetic waves. Photons travel with the wave at about 300‚000 k/s. also known as the speed of light. The more energy the photons have‚ the brighter

Imagery is a mental technique that athletes can use to program the human mind to respond as desired… Discuss A Discussion of the Efficacy of Imagery Techniques for Novice and Professional Athletes Athletes are always on the look out for techniques that will allow them to get better at their game. Whether it is a golfer who is looking to break his best score or a hockey goalie who is trying to get a shutout in the next game he plays‚ amateur and professional athletes are constantly trying to

Seismic Waves What are seismic waves? Seismic waves are the waves of energy caused by breaking of rock within the earth or an explosion. These waves are the energy that travels through the earth and is recorded on seismographs. There are many different types of these waves‚ but the two main ones are the body waves that usually travel though in inner layer of the earth‚ and the surface waves that only move around the surface of the planet. Body waves travel through the inner layer of the earth
