What is a Harmonic Wave?

A wave is an acoustic disturbance that travels through space. Individual molecules wobble back and forth as it passes through space. If the wave is harmonic, all particles are moving in a basic harmonic motion.

Harmonic Waves Formula

A wave is a disturbance that propagates through space in general. Individual molecules oscillate back and forth when a wave arises. The particles in a harmonic wave are all moving in a basic harmonic motion.

The following is the formula for calculating the displacement of a point along with a harmonic wave: y = A * sin[(2π / λ) * (x - vt) + Φ]

  • Where, y = displacement of a given point along with the wave,
  • x = position of that point (its distance from the source),
  • t = time point,
  • v = wave velocity,
  • λ = wavelength,
  • A = amplitude, and
  • Φ = initial phase of the wave.

Harmonic Wave Equation Examples

Question 1:Calculate the harmonic wave displacement of a point with an amplitude of 25 cm, a wavelength of 15 cm, a velocity of 8 m/s, a distance from the source of 7 cm, a time of 10 seconds, and an initial phase of 14 radians.



Time point t = 10 s

Wave velocity v = 8 m/s

Distance from the source x = 7 cm

wavelength λ = 15 cm

Amplitude A = 25 cm

Initial phase of the wave Φ = 14 radians

Harmonic Wave Formula y = A * sin[(2π / λ) * (x - vt) + Φ]

y = 25 * sin[(2Ï€ / 15) * (7 - 8 * 10) + 14]

y = 25 * sin[(0.418) * (7 - 80) + 14]

= 25 * sin[(0.418) * (-73) + 14]

= 25 * sin[-30.51 + 14]

= 25 * sin(-16.51)

= 25 * (-0.284)

= -7.104

Hence, the displacement of the point is -7.104 cm.

FAQs on Harmonic Wave Equation Calculator

1. What is the definition of a harmonic wave equation?

The wave has a frequency that is a positive integer factor of the fundamental frequency is known as a harmonic wave. The first harmonic wave is the initial wave.

2. How do you use a harmonic wave equation calculator to compute the point displacement?

To examine the displacement of a location along with the harmonic wave with a full explanation, simply enter all known numbers in the calculator's input fields and press the calculate button.

3. How do you find out how long a period is?

A periodic motion's time period is the amount of time that passes between two points where the motion is in the same position or phase. 2 pi/w = T

4. What are voltage harmonics, and what do they mean?

A sinusoidal wave with a frequency that is an integer multiple of the fundamental frequency is a harmonic of a voltage or current waveform in an electric power system.

5. In simple harmonic motion, how do you calculate the time interval?

x ( t ) = A cos ( ω t + ϕ ) This is the generalised equation for SHM. where, t represents time in seconds, is the angular frequency in inverse seconds, A represents amplitude in metres or centimetres and is the phase shift in radians
