Letω = angular speed (we can't do velocity with the given information),
f = frequency
ω = 2
π f
ω = 2
π (50 * 1000 Hz) = 100,000
π rad/sec ~= 314,159 rad/spec
with a sine wave
The period is 1 millisecond.
sine wave, with a period of 2pi/w
360 degrees
5 cycles.
these are angular velocity & time. Sine(wt)
Velocity equals frequency times wavelength
Assuming the sine wave's angular frequency is what's changing, the motor will speed up and slow down in proportion to that frequency.
By shifting the sine wave by 45 degrees.
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.
v=lambda*f v is velocity, lambda is wavelengt, f is frequency Units are m/s, meters, Hertz Or v=w/k v is velocity, w(supposed to be greek letter omega) is angular frequency, and k is the wave number Or If you want to get complicated the velocity of a wave can be seen in the wave equation. This requires partial derivatives, look into it for calculus based physics
a phase shifted sine wave of a different amplitude.
cos wave
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.
It's called a sine wave because the waveform can be reproduced as a graph of the sine or cosine functions sin(x) or cos (x).
The sine wave, with its repeating pattern, can represent a single frequency with no harmonics.
