to overcome the short coming of the Short Time Fourier Transform (STFT)‚ which can also be used to analyze non-stationary signals. While STFT gives a constant resolution at all frequencies‚ the Wavelet Transform uses multi-resolution technique by 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

Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years.
