You can't tell. The speed of a wave depends on what's doing the waving and what medium
it's propagating through. It doesn't depend at all on the frequency of the wave, at least not
in a nondispersive medium.
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
The voltage and current are delivered in a sine wave that goes positive and then negative at 60 cycles per second. Google sine wave to see what a sine wave looks like.
The wavelength of a 25Hz sine wave can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound is approximately 343 meters per second, the wavelength of a 25Hz sine wave would be around 13.72 meters.
By shifting the sine wave by 45 degrees.
The length of a Hz sine wave can be calculated using the formula: length = 1/frequency. For example, for a sine wave of 1 Hz, the length would be 1 second. This formula is derived from the relationship between frequency (number of cycles per second) and the period (duration of one cycle), where period = 1/frequency.
One cycle of a 125hz sine wave would last .008 seconds. Hz (hertz) refers to the frequency of the wave itself, that is, how many times the wave cycles in a second. To find the cycle length, then, simply divide 1 second by the frequency, in this case: 1/125 = .008.
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
The voice is not a sine wave.
Period = 1 / frequency = 1/272 = 0.003676 second (rounded)
Sine wave is considered as the AC signal because it starts at 0 amplitude and it captures the alternating nature of the signal. Cosine wave is just a phase shift of the sine wave and represents the same signal. So, either sine or cosine wave can be used to represent AC signals. However, sine wave is more conventionally used.
a phase shifted sine wave of a different amplitude.
