Radio waves for Communication Radio waves are electromagnetic waves with wavelengths larger than the infrared light. Like all other electromagnetic waves‚ they travel at the speed of light. The wavelengths can vary from the size of a football field to the size of a football. They can be produced naturally by large stars and by lightning. Man-made radio waves are used for transmitting signals and currents. Specific Properties of Radio Frequency (RF) Current Radio frequency is the frequency of radio

The Three Big Waves of Feminism First-Wave Feminism: Women’s Right to Vote In 1776‚ the then First Lady of the United States was the first to raise her about women’s rights‚ telling her husband to “remember the ladies” in his drafting of new laws‚ yet it took more than 100 years for men like John Adams to actually do so. With the help of half a dozen determined‚ and in this case white upper-middle-class‚ women the first-wave feminism‚ which spans from the 19th century to the early 20th century

which different frequencies are analyzed with different resolutions. A wave is an oscillating function of time or space and is periodic. In contrast‚ wavelets are localized waves. They have their energy concentrated in time or space and are suited to analysis of transient signals. While Fourier Transform and STFT use waves to analyze signals‚ the Wavelet Transform uses wavelets of finite energy.
