Problem

A transverse wave on a string travels at 20, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction . A graph of the height of the wave along the x-direction at a certain moment is shown below.
What is the frequency of the wave along the string?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
start text, H, z, end text
