Unformatted text preview: amplitude of the electric field of the waves is E at a distance of r from the source. At a distance of 2 r from the source, the amplitude of the electric field of the waves will be: A. 2 E D. E – 3.0 db B. E /2 E. E – 6.0 db C. E /4 _E _ 3. A source of sound waves emits waves uniformly in all directions. The sound level of the waves is β at a distance of r from the source. At a distance of 2 r from the source, the sound level of the waves will be: A. 2 D. – 3.0 db B. /2 E. – 6.0 db C. /4...
