Four wave functions are given below. I. y(x, t) = 5sin(4x  20t + 4) II. y(x, t) = 5sin(3x  12t + 5) III. y(x, t) = 5cos(4x + 24t + 6) IV. y(x, t) = 14cos(2x  8t + 3) Use this exhibit to answer the following question(s). Rank the wave functions in order of the magnitude of the wavelengths, from least to greatest.
 a. IV, II, I, III
  b. IV, I, II, III
  c. I, II, III, IV
  d. IV, II, III = I
  e. I = III, II, IV
