Electromagnetic Waves It was once the great Scottish physicist James Clerk Maxwell (1831-1879) who had presented that electric and magnetic fields unstable together can form a spreading wave‚ appropriately called an electromagnetic wave. The properties of an electromagnetic wave are as follows: 1. They can travel through a vacuum at the same high speed‚ which is much faster than other types of waves that travel through a material. 2. They show the normal wave properties of reflection‚ refraction

STATISTICS HOMEWORK PROBLEM 1 Part of a usability study to assess the usability of voting machines included a measure of the time on task (TOT) of voters casting ballots. The data are for the same ballot cast on two different voting machines at the same location. A few background items: * The voters (participants/users) are a homogeneous group. * Voters were randomly assigned to theo vting machines. * Due to items 1 and 2 above‚ assume the two groups of

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

INFRARED WAVES * Infrared (IR) light is electromagnetic radiation with a wavelength longer than that of visible light How They’re Made: Infra red waves are just below visible red light in the electromagnetic spectrum ("Infra" means "below"). You probably think of Infra-red waves as heat‚ because they’re given off by hot objects‚ and you can feel them as warmth on your skin. Infra Red waves are also given off by stars‚ lamps‚ flames and anything else that’s warm - including you. The detector

main characters in the book The Sound of Waves by Yukio Mishima. In both stories‚ the romantic couples had a relationship that was undesired amongst their families‚ they both had obstacles that kept them from each other‚ and both couples had friends that influenced the outcomes of their relationships. The complicated ramifications of two people in love are very clear and obvious in both of these stories. It is the theme that encompasses both books and makes them so much alike in content.

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
