Two sinusoidal waves, identical except for phase, travel in the
same direction along a string, producing a net wave
y´(x, t) = (3.50 mm) sin(14.0x
- 3.50t + 0.840 rad),
with x in meters and t in seconds. What are
(a) the wavelength λ of the two waves,
(b) the phase difference between them, and
(c) their amplitude ym?
Homework Answers
A)
Wavelength, lambda = 2 pi/14 = 0.45 m
B)
Phase difference, phi = 2 x 0.84 = 1.68 rad
C)
2 ym cos(0.84) = 3.5
Amplitude, ym = 2.62 mm
