For the wave described by y = 0.02 sin (kx) at t = 0 s, the first maximum at a positive x coordinate occurs where x = 4 m. Where on the positive x axis does the second maximum occur?
 a. 20 m
  b. 18 m
  c. 24 m
  d. 28 m
  e. 16 m

Question 2

Write the equation of a wave, traveling along the +x axis with an amplitude of 0.02 m, a frequency of 440 Hz, and a speed of 330 m/sec.
 a. y = 0.02 sin 880p(x/330 - t)
  b. y = 0.02 cos 880p x/330 - 440t
  c. y = 0.02 sin 880p(x/330 + t)
  d. y = 0.02 sin 2p(x/330 + 440t)
  e. y = 0.02 cos 2p(x/330 + 440t)
