Muule 14. Superposition and Standing Waves: Homework < Module 14. Superposition and Standing Waves: Homework Problem 16.37 - Enhanced - with Feedback 3 of 11 interference. Review Constants Periodic Table Two loudspeakers emit identical sound waves along the 2-axis. The sound at a point on the axis has maximum intensity when the speakers are 30 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 60 cm. es Part B alog If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum? Express your answer with the appropriate units. O ? OHA Value Ad cm Submit Previous Answers Request Answer Next Previous

Answer 1

$\Delta x_1 =30 cm$

Дгр — 60ст

$\Delta x_2-\Delta x_1 =\lambda /2$

$\60-\30 =\lambda /2$

$\lambda =60cm$

now let x is distance where sound intensity again will be zero is given by

$x=\Delta x_1+\lambda$

$x=30+60$

x=$\Delta d$=90cm

please like my solution. thank you
