1-9 Interference of Waves
Two waves traveling along a string are
described
by:
where x and y are expressed in meters and t
is in
seconds.
a.
What is the speed and wavelength
of the resultant wave?
b. What
is the transverse speed for the particles in the string at x = 5 cm and t = 2
s?
Example
1
a.
The speed of the
resultant wave is
It is the same as the speed of wave 1 and
wave 2.
Answer
a.
The wavelength of the
resultant wave is
It is the same as the wavelength of wave 1
and wave 2.
b. The resultant wave is
The transverse speed at x = 5
cm and t = 2 s is
