what is the amplitude of the resultant wave?

1. Two waves having the same frequency, wavelength, and amplitude are traveling in the same direction. If they differ in phase by I?/2 and each has an amplitude of 0.05 m, what is the amplitude of the resultant wave?
2. The constant g for helium (and all monatomic gases) is 1.67. If a man inhales helium and then commences to speak, he sounds like Alvin of the Chipmunks. Why?
