A classic example of polarization is for waves travelling down a guitar string. The direction of polarization is the direction in which the string is plucked, while the waves travel down the string. Answer and Explanation: The reason sound waves can not be polarized is because they are longitud...

When we want to characterize audio systems, we use test tones (aka sinusoids) or sinusoidal sweeps. These are simple audio signals made up ofsine wavesat defined frequencies. Alone, test tonesdo not sound musicalbut are actually the basic building blocks of all complex, musical waveforms and a...
Consider the function f(x)= arcsin(x) + arccos(x). (Here arcsin (x) and arccos(x) are the inverse sine and inverse cosine functions.) (a) Evaluate f(0) (b) Show that f'(x) = 0 on (-1, 1). (c) Use (a) and (b) to explain why arcsin(x) + arccos(x) = π/2 ...
A sinusoidal carrier wave of frequencu 1 MHz and amplitude 100 V is amplitude modulated by sinusoidal voltage of frequency 4 kHz producting 50% modulation. The frequencies of lower and upper side band terms are respectively, View Solution ...
SWA consist of time-varying sinusoidalwaves, or sine waves, that track the centre frequencies ofthe energy bands (formants) of natural speech to reproducethe changes in these frequency peaks across time. SWAare typically composed of three sinusoidal waves thatreproduce the changes in the rst ...
Carefully manipulated sinusoidal voltage (or current) signals are the foundation of the modern wireless age. With this in mind, we can ask ourselves the more relevant questions: Why is electromagnetic radiation the preferred method? Why are other types of wireless communicatio...
The justification for such general statements is that any periodic waveform of an endogenously spiking neuron can be decomposed into a sum of cosine waves. Based on our theoretical proof that any SBF model with noisy cosine oscillators has a Gaussian output function that obeys the scalar property,...

In Hugyen's principle of wave theory why the waves are move in forward direction not in backward direction means they move forward as a new source why not in backward direction? Why don't we have a way to model gravity? Why does area of the surface have no role in motion due...
