How does the phenomenon of interference play a role in the production of bow waves or shock waves?
Solution 42E The superposition of two or more waves may increase or decrease the amplitude of the resultant wave. This phenomenon is known as interference. Bow waves are produced by the overlapping of multiple circular shaped waves when the speed of a bug (say) is either equal to or more than that of the wave. These circular shaped waves overlap to form a bow wave. Therefore, a bow wave is the interference of multiple circular shaped waves generated by a bug swimming in water. Similarly, shock waves are produced by the overlapping or interference of several spherical shaped waves generated by a supersonic aircraft.
