What does resonance result in? quieter sounds, frequency, amplitude

Question:

What does resonance result in?

A)Quieter sounds B) frequency, C) amplitude D) Louder sounds.

Resonance results in louder sounds.

Explanation:

In fact, the point at which the sound show maximum amplitude is termed as resonance. Since there is an increase in amplitude, the sound turns louder, and louder. Resonance is the situation, where one body vibrates after being effected by another vibrating body. Let us take an example of two bodies ‘A’ and ‘B’ at vibration.

Let the body A is in vibration at a particular frequency. And then, let the body ‘B’ disturbs with its vibration. Now, ‘A’ imparts some additional frequency, from ‘B’, which leads to resonance. So, if the amplitude increases, the sound produced is huge, and hence louder.

where's the following? you gotta add it to know what the choices are

explanation:

conservation of mass

mass before something happens = mass afterwards
