Fiber optic telecommunications relies on which of the following properties of waves? a. Reflection b. Refraction c. Diffraction d. Interference e. Both a and b 2. Briefly describe the cause of a sonic boom? When the sound source exceeds the speed of sound, the waves produced from the source “catch-up” with the waves that have already been emitted. This produces a wake of air molecules that rush back together to produce a sonic boom. This is ultimately caused by the Doppler effect. In the figure below, the dotted line represents the direction of motion of the object. Wavefront of Sonic Boom
