question 22

Multiple Choice

Two separated sources emit sinusoidal traveling waves that have the same wavelength λ\lambda and are in phase at their respective sources. One travels a distance  Two separated sources emit sinusoidal traveling waves that have the same wavelength  \lambda  and are in phase at their respective sources. One travels a distance   to get to the observation point while the other travels a distance   The amplitude is a minimum at the observation point if   is: A)  an odd multiple of  \lambda /2 B)  an odd multiple of  \lambda /4 C)  a multiple of  \lambda  D)  an odd multiple of   \pi /2 E)  a multiple of   \pi to get to the observation point while the other travels a distance  Two separated sources emit sinusoidal traveling waves that have the same wavelength  \lambda  and are in phase at their respective sources.
