How do trig functions greet each other?
with a sine wave
What is the period of a 1kHz sine wave?
The period is 1 millisecond.
What is phase shift when a sine wave with the maximum amplitude at time zero?
360 degrees
What equation is this x equals a sin wt?
sine wave, with a period of 2pi/w
When a sine wave has a frequency of 50 Hz in 10 seconds it goes through?
5 cycles.
What are two variables of a sine wave?
these are angular velocity & time. Sine(wt)
What is the relationship between the frequency and the wavelength and angular velocity of electromagnetic wave?
The frequency of an electromagnetic wave is inversely proportional to its wavelength, meaning a higher frequency corresponds to a shorter wavelength. The angular velocity of an electromagnetic wave is directly proportional to its frequency, so an increase in frequency will lead to an increase in angular velocity.
Explain how sin wave will be always periodic?
A sine wave is a periodic function because it repeats its pattern over regular intervals. This periodicity is due to the angular frequency of the wave, which controls how many complete cycles of the wave occur in a given time period. As long as the angular frequency remains constant, the sine wave will continue to repeat its pattern indefinitely.
How is the speed of an AC motor that's being driven by a constantly changing sine wave voltage effected?
Assuming the sine wave's angular frequency is what's changing, the motor will speed up and slow down in proportion to that frequency.
How do you generate cos wave from sine wave?
By shifting the sine wave by 45 degrees.
The phase velocity vp of traveling wave is?
A wave is propagating along the string that has a length of 2 m and is under a tension of 48 (a)Determine the velocity of the wave along the string (c)The mass of the string N. The displacement of the string is given by S(y,t) = 0.024sin(0.6y –7t) (b)The wavelength of the wave (d)The power carried by t
What is a good mathematical model for representing transverse waves?
A good mathematical model for representing transverse waves is the sine or cosine function, typically written as y(x,t) = Acos(kx - ω*t), where A is the amplitude, k is the wave number, x is the position, ω is the angular frequency, and t is time. This model describes how the displacement of the wave varies with both position and time.
Definition of sine wave?
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
How could you print out a sine wave of your voice on a laser printer?
The voice is not a sine wave.
Formula for velocity of a 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
Why you are considering sine wave as ac but not cosine wave?
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.
What will be the output of differentiator if the input is sine wave?
a phase shifted sine wave of a different amplitude.
