Consider the situation where two speakers facing the same direction are two metres apart. The speakers are in phase, that is, they are producing exactly the same frequency and their movements are exactly synchronised with each other. The two speakers are separate sources of sound waves that diffract at the speaker aperture and then constructively and destructively interfere with each other. What name is given to the points where constructive interference occurs?

where are the vectors ?

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
