The standing wave pattern diagrammed to the right is produced in a string fixed at both ends. The speed of waves in the string is 2 m/*. What is the frequency of the standing wave pattern?
A) 0.25 Hz
B) 1 Hz
C) 2 Hz
D) 4 Hz
E) 8 Hz
The correct option is: (D) 4 Hz
Explanation:
From diagram, wavelength = 0.5 m. Find the frequency with v = f λ
