Explanation Given Data: Two identical loudspeakers 2 m apart are emitting sound waves into a room where the speed of sound is 340 m s . Abby is standing 5 m in front of one of the speakers, perpendicular to the line joining the speakers and hears a maximum in the intensity Formula Used: Consider the expression for wavelength. λ = v f Here, v is the velocity of the wave, and f is the frequency of the wave. Consider the expression for path length difference of constructive interference. Δ d = m λ Here m is the numerical value of λ , and λ is the wavelength. Modify the equation to find λ . λ = Δ d m Substitute v f for λ . v f = Δ d m Modify the equation to find f . f = v m Δ d (1) Explanation: To find the lowest possible frequency for the maximum intensity of sound, consider m = 1 . The illustration for the position of both the speakers and A is shown in Figure 1. Find the value of r 2 using Pythagoras Theorem

Students have asked these similar questions

A capacitor with a capacitance of C = 5.95×10−5 F is charged by connecting it to a 12.5 −V battery. The capacitor is then disconnected from the battery and connected across an inductor with an inductance of L = 1.55 H . At the time 2.35×10−2 s after the connection to the inductor is made, what is the current in the inductor? At that time, how much electrical energy is stored in the inductor?

Can someone help me with this question. Thanks.
