Two loudspeakers both emit sounds with a frequency of 340Hz. Both sounds have equal amplitude and phase. The amplitude is A. The speakers are 4m apart and face each other. The speed of sound in air is 340m/s

#1 What is the wavelength of the sound?

#2 What is the amplitude of the sound when you’re 1m from one loudspeaker, and 1.5m away from the second loudspeaker?

Two sound sources with the equal amplitudes are played over two loudspeakers. Their frequencies are 800Hz and 804Hz.

#3 What low frequency will be heard?

#4 What high frequency will be heard?

#5 When two coherent waves combine constructively to create a maximum, what is the smallest phase difference possible in Radians?

When two coherent waves combine destructively to create a minimum, what is the smallest phase difference possible

#6 In degrees

#7 In radians

#8 What happens when the two waves have a phase difference of 90 Degrees?
