Actually, both of these use empty space as a medium - but the point is that they require no additional material, as when a sound wave requires atoms to propagate.
The material through which a wave travels is called the medium.
No, a transverse wave requires a medium to propagate because the particles in the medium must move perpendicular to the direction of the wave's energy transfer. Without a medium, such as in a vacuum, transverse waves cannot propagate.
Refraction describes the bending of a wave as it travels into a different medium, due to the change in speed of the wave as it enters the new medium.
The speed at which a wave travels through a medium is called the wave speed or wave velocity. It is determined by the properties of the medium, such as its density and elasticity, and is independent of the wavelength and frequency of the wave.
A medium.
The general term for what a wave travels through is a medium, but in the case of earthquakes the wave travels through the ground.
Up to a crest, then down through a trough, then back. APEX :P
The material through which a wave travels is called a medium.
The frequency of the wave remains the same when it travels from a denser to a less dense medium. However, the wave will change its speed and wavelength.
The speed at which a wave travels through a medium depends on the properties of the medium. In general, the denser the medium, the faster the wave will travel. The speed of a wave can also be influenced by factors like temperature, pressure, and elasticity of the medium.
A wave is a disturbance that travels through a medium or space. It carries energy from one place to another without transporting matter.
The frequency and wavelength of the wave cannot change as it travels from one medium to another.
