longitudinal wave that travels through all forms of matter. The air molecules vibrate in the same direction as the sound wave moves. The modes of vibrations associated with resonance in objects like strings or air columns have patterns called standing waves. The resonance occurs when the standing wave moves in the opposite direction to the medium’s movements‚ or when it arises from the combination of reflection and interference such that the reflected waves interfere with the incident waves.

“The third-wave of feminism encompasses several diverse strains of feminist activity and study” (Nicholson‚ 33). The third-wave ascended somewhat as an answer to the repercussions in contradiction of the initiatives and movements created in the 1960s through the 1980s. It is a challenge to increase the feminist knowledge‚ including women with a diverse set of personalities and characteristics‚ recognizing that women are of “many colors‚ ethnicities‚ nationalities‚ religions‚ and cultural backgrounds”

The “waves” metaphor is used to denote continuity of movement containing swells and troughs rather than discrete‚ isolated periods of political involvement. The theoretical underpinnings of the third wave‚ therefore‚ come from three widely divergent streams of thought that coexisted during this time. Many third-wave writers talk

With a view of third-wave feminism and micro politics‚ I will ascertain if there is a politic present in the delivery of the message.

Moving on‚ since the crash of the First Wave of feminism‚ we have seen an on and off switch of freedoms and limitations. The 1920’s or better known as the Roaring Twenties brought out women’s votes to play and the presence of “flappers” led women to unprecedented freedoms when it came to the way they dressed and acted in public settings. After the Stock Market Crash‚ the Great Depression‚ and diving into World War II‚ more women were brought into the working force like never before. As Claudia Goldin
