The medium of earthquake waves is earth. n a radio wave with a. a longitudinal wave (such as a sound wave) propagated by the elastic compression of the medium —called also compression wave…. Wavelength and frequency. However, the medium vibrates back and forth and transfers the energy; the medium is not carried along with the sound wave. Matter that waves are traveling through is called a medium. A transverse wave is when the wave is vibrating perpendicular to the direction the wave is traveling. Low to Medium Frequencies. During daylight hours, medium waves are usually strongly absorbed by the ionosphere and propagate only as surface waves that follow the curvature of the earth’s surface. When all air is removed there is no medium for the sound waves to travel through so no sound is heard. Inherently, all waves carry energy from one place to another when they move. These waves travel when molecules in the medium collide with each other passing on energy. What does mechanical wave mean?
