independent of the direction of propagation of the waves and thus produce relatively different effects for the two directions of transmission.

Refraction of sound waves by two layers of air at different temperatures as a result of the change ... Uno Ingard, "A Review of the Influence of Meteorological Conditions on Sound Propagation," ...

AMONG the facts to be explained in a satisfactory theory of the propagation of radio waves over the earth's surface are the curvature of the rays in transmission between stations far apart ...

These waves are higher frequency than surface waves. P waves are also known as compressional waves, because they push and pull. Particles subjected to a P wave move in the same direction that the wave ...

The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...
