FICURE 9 illustrates the wave pattern of a moving source. Choose the CORRECT statements: FIGURE 9 I The speed of the wave increases as the source is moving towards point 2 . II The speed of the wave is constant as the source is moving towards point 2 . III The frequency of the wave is higher at point 1 as compared to point 2 . IV The wavelength of the wave is longer at point 1 as compared to point 2 . V The wavelength of the wave is shorter at point 1 as compared to point 2 . VI An observer at point 1 will perceive a smaller frequency as compared to an observer at point 2. A. I and III B. I and IV C. II and III D. I, III and IV E. II, III and IV F. II, IV and VI G. II, V and VI H. I, III, IV and VI
