Two speakers one directly behind the other are each, Ask an Expert

Academics

Q. Two speakers, one directly behind the other, are each generating a 295-Hz sound wave. What is the smallest separation distance between the speakers that would produce destructive interference at a listener standing in front of them? Take the speed of sound to be 342 m/s.

Q. A child's toy consists of a piece of plastic attached to a spring. The spring is compressed against the floor a distance of 2.00 cm, and the toy is free. If the toy has a mass of 90 g and rises to a highest height of 55.0 cm, compute approximately the force constant of the spring.
