The diagram below shows wavefronts of waves incident on a boundry XY between medium M, and another medium M, wavefronts Y normal direction of travel 309 M, M The angle between the normal and the direction of travel of the wavefronts is 30°. The Frequency of the wave in M, is 36 Hz. The speed of the wave in M, is 0.8 m/s. The speed of the waves in M, is 0.95 m/s Calculate the angle between the direction of travel of the wavefronts in M2 and the normal. What is the frequency of the wave in M2? What is the wavelength of the wave in M1? What is the wavelength of the wave in M2?
