A sound source is placed in the center of a very wide and long room that has a low ceiling. Assume that the ceiling and floor are constructed of a material that absorbs the sound completely. In this situation, how would the intensity of the sound heard vary if a person moves from a distance of 10 meters from the source to a distance of 20 meters from the source?
1.The sound would have about ¼ the intensity 20 m from the source that it has 10 m from the source.
2.The sound would have about ½ the intensity 20 m from the source that it has 10 m from the source.
3.The sound would have about the same intensity 20 m from the source that it has 10 m from the source.
4.The sound would have about twice the intensity 20 m from the source that it has 10 m from the source.
