Negative interference

Explanation:

Thinking process:

In the physics, the interference is when there is either an additive or destructive effect in the effects of sound. In the first scenario, the sound is loudest when the speakers are separated at 22 cm apart. This is as a result of constructive interference. Constructive interference results from the additive effect of waves to give the highest pitch. However, as the speakers are moved further, the sound decreases. This is because of the destructive interference where the waves are not much of addition.
