A wave pulse travels along a stretched string at a speed of 200 cm/s. What will be the speed if:
a. The string’s tension is doubled?
b. The string’s mass is quadrupled (but its length is unchanged)?
c. The string’s length is quadrupled (but its mass is unchanged)?
Note: Each part is independent and refers to changes made to the original string
Is the displacement ,
where x is in m and t is in s, a possible traveling wave? If so, what
is the wave speed?
A sinusoidal wave travels along a stretched string. A particle on the string has a maximum speed of 2.0 m/s and a maximum acceleration of 200 m/s2. What are the frequency and amplitude of the wave?
Cell phone conversations are transmitted by high-frequency radio waves. Suppose the signal has wavelength 35 cm while traveling through air. What are the (a) frequency and (b) wavelength as the signal travels through 3-mm-thick window glass into your room?
The displacement of a wave traveling in the positive x-direction
is , where x is in m and t is in s.
What are the (a) frequency, (b) wavelength, and (c) speed of this wave?
