Find the lowest two frequencies that produce a maximum sound intensity at the positions of Moe and Curly.

hello your question has some missing parts below is the complete question

and the missing diagram

The two speakers emit sound that is 180° out of phase and of a single frequency,ƒ, Find the lowest two frequencies that produce a maximum sound intensity at the positions of Moe and Curly.

answer : 1316.2 hertz

Explanation:

The frequency that produce the maximum sound intensity can be calculated using the relation below

dsin ∅ = n A

where A = dsin ∅ / n  when n = 1 . d = 0.800

A = 0.800 * ( 1 / 3.162 )

A = 0.253 m

speed of sound = 333 m/s

frequency = speed / A

=   333 / 0.253 =  1316.2 hertz

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
