The correct answer for the question that is being presented above is this one: "(a)4." Suppose that during any period of 1/4 second there is one instant at which the crests or troughs of component waves are exactly in phase and maximum <span>reinforcement occurs, in 1 second, there will be 4 beats.</span>

<h2>Answer:</h2>

<u>The correct option is</u><u> (A) 4 beats</u>

<h2>Explanation:</h2>

When two sound waves of different frequency approach the listener, the alternating constructive and destructive interference causes the sound to be alternatively soft and loud - a phenomenon which is called "beating" or producing beats. If one beat occur in 1/4 of a second, this means that, a second is divided into four parts and one beat occur in each part. Therefore in a second, there will be four beats.
