Longitudinal wave and seismic P-waves (created by earthquakes and explosions). In longitudinal waves, the displacement of the medium is parallel to the propagation of the wave, and waves can be either straight or round. A wave along the length of a stretched Slinky toy, where the distance between coils increases and decreases, is a good visualization. In the case of longitudinal harmonic sound waves, the frequency and wavelength can be described by the formula where: The quantity "x"/"c" is the time that the wave takes to travel the distance "x". The ordinary frequency ("f") of the wave is given by The wavelength
A Wave, a WAC and a Marine no idea what I wanted to do. But he put up the money and we decided on the crazy story "A Wave, a WAC and a Marine"." Karlson called the movie "probably the worst picture ever made... It was a nothing picture, but I was lucky because it was for Monogram and they didn't understand how bad it was because they had never made anything that was any good." However it did launch Karlson's directing career. A Wave, a WAC and a Marine A WAVE, a WAC and a Marine is an American 1944 musical comedy film directed by Phil
