25.12 cm, produce

interference in which the maximum amplitude is 0.10 m and minimum

0.04 m. Estimate (a) the angular frequency of each wave, (b) the
propagation

constant (k) of each wave, (c) the amplitude of each wave and (d)
resultant

intensity, if the phase difference between the waves is 3.14
radian.

Answer #1

a frequency of 100 Hz, a wavelength of 2 cm, and an amplitude of
0.02 m. What is the amplitude of the resultant wave if the original
waves differ in phase by each of the following values?
(a) π/6 cm
(b) π/3

Two waves traveling on a string in the same direction both have
a frequency of 269 Hz, a wavelength of 0.29 m,
and an amplitude of 0.44 m. What is the amplitude of the
resultant wave if the original waves differ in phase by π/3
rad?
Tries 0/10
What is the phase difference between the two waves if the
amplitude of the resultant wave is 0.22 m?

Two waves of amplitude 0.53 m and 0.58 m interfere. If the
resultant intensity at a given point is 1.2321 W/m2. Predict
whether the waves produce constructive or destructive interference
at this point and also maximum and minimum amplitudes

In a medium, sinusoidal waves propagate with a
wavelength of 0.30 m, a frequency of 25 Hz, and an amplitude of 4
mm (assume it propagates to the right). At x = 0 m and t = 0 s, the
deviation is y = 4 mm. Determine:
a. Speed of propagation and wave period
b. The distance between two points with different phases π/

Two traveling waves with the same amplitude A, frequency f, and
wavelength λ, but out of phase with each other by one quarter of a
wavelength, are both traveling to the right and superpose in space.
Find the amplitude, wavelength, and frequency of the resulting wave
in terms of the given symbols. Write the equation of the resulting
traveling wave y ( x , t ).

Two loudspeakers emit coherent in phase sound waves with at a
frequency of 68.8 Hz. The speed of sound is 344.0 m/s.
Point q is vertically located 2.0 m from the bottom speaker and

constructive interference, complete destructive interference, or
neither?? Explain your answer.
