Wave Motion (Physics)

Sound waves are characterized by the motion of particle in the medium and are longitudinal (in air and in any fluid medium) mechanical waves while Radio-waves, X-rays and light waves are electromagnetic waves.

Sound waves are characterized by the motion of particle in the medium and are longitudinal (in air and in any fluid medium) mechanical waves while Radio-waves, X-rays and light waves are electromagnetic waves.

Sound waves in air (and in any fluid medium) are longitudinal waves because particles of the medium through which sound is transported, vibrate parallel to the direction that the sound wave moves.

The distance between two consecutive compressions or rarefactions is the wavelength of the sound wave which is a longitudinal wave in air or in any fluid medium.

The speed of sound is the product of the wavelength and frequency of the wave. Wavelength in a transverse wave is the distance between two consecutive crests or troughs.

When we pluck the string of an instrument, like the Sitar, the sound that we hear is not only that of the string. The whole instrument is forced to vibrate, and it is the sound of the vibration of the instrument that we hear.

When a string under tension is set into vibration, a transverse wave travels along the wire and is reflected at the fixed end. A transverse stationary wave is thus formed.

The ionosphere is a region of Earth's upper atmosphere from about 50 to 400 miles altitude. It is ionized by solar radiation. It has practical importance because among other functions, it influences radio propagation to distant places on Earth.

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz Owing to its high frequency, an ultra-high frequency (UHF) wave can neither travel along the trajectory of the ground nor get reflected by the ionosphere.

The signals having UHF are propagated normally through the line of sight communication which is actually space wave propagation. The radio waves having high frequencies are basically called as space waves.

Sound waves cannot travel in vacuum. It is transmitted by the movement of particles along with the direction of the motion of the sound wave.

More generally, sound is a mechanical disturbance which is dependent upon a medium to travel. It can be transmitted through solid, liquid, and gas.
