Question

Quizplus · Accepted Answer

Low frequencies have longer wavelengths and are less easily absorbed by air molecules, allowing them to travel farther distances. High frequencies, on the other hand, have shorter wavelengths and are more easily absorbed by air molecules, causing them to lose energy and become weaker as they travel. Ultrasonic frequencies are above the range of human hearing and are not relevant to this question.
