The third-wave feminists are critical to the first and second waves because it ties all of the women’s movements previous accomplishments to all women‚ regardless of race‚ color‚ sexual orientation‚ and class. Without the third-wave feminists only white women would have the luxury of being able to vote‚ being provided equal employment opportunity‚ being heard when faced with sexual harassment and marital rape‚ and being able to broadcast the discrimination of gender. America wouldn’t be the country

Before beginning our 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

to point through a medium is called a ___. a. period b. periodic wave c. wavelength d. pulse Answer: D A wave is a continuous and repeating disturbance of a medium and a pulse is a single disturbance. 2. If the particles of the medium are vibrating to and fro in the same direction of energy transport‚ then the wave is a ____ wave. a. longitudinal b. sound c. standing d. transverse Answer: A In longitudinal waves‚ particles of the medium vibrate to and from in a direction parallel

Electromagnetic waves in space See the book “Optics” by Hecht sections 3.2 and 3.3 Speed of light: EM waves travel in a vacuum with speed c = c = 299‚792‚458 ms-1 exactly They are transverse waves with (vector) E and B field orthogonal to each other‚ for this section bold indicates vector quanties. When far from the source (many wavelengths) the E and B fields are in phase The vector E x B points in the direction of motion Travelling waves can be written as E = E 0 ⋅ ei ( kx −ωt ) and B = B 0 ⋅ ei

Unit: Sinusoidal Waves Subject: Advanced Algebra/ Trigonometry Overarching Question: What are real life applications of Sinusoidal Waves? First and Foremost‚ Sinusoidal Waves are waves that can be described to have a sine curve‚ usually repetitive. Sine waves are a part of the mathematic topic‚ Trigonometry. However‚ these types of waves may be found in various other scenarios. For instance‚ many are found in nature‚ you just have to observe with care. This means to say that they aren’t just

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

It imports TV series and movies from neighboring Asian countries. Imported movies are then dubbed in Filipino and streamed in our country. ABS-CBN‚ one of the top TV stations in the country‚ started to explore foreign TV series last 2003. This was “Meteor Garden‚” a Taiwanese drama series. Because of the boom of the

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
