Slower than the speed of an electromagnetic wave in a vacuum by about 3 parts in 10,000. The speed of light in any medium is related to the refractive index of that medium. The refractive index of vacuum is 1, the refractive index of air is about 1.0003.
It is noteworthy that the speed of electromagnetic waves in media other than a vacuum depend on their wavelength. In standard air, the speed is c/ns where ns (the refractive index) is given by the dispersion equation below in which σ is equal to one over the vacuum wavelength. It is also interesting that the refractive index is changing over time as more and more carbon dioxide accumulates in the atmosphere.
(ns − 1) × 108 = 8 342.54 + 2 406 147(130 − σ2)−1 + 15 998(38.9 − σ2)−1
Mechanical waves need a medium to travel through, such as air, water, or solids. These waves propagate by transferring energy from one particle to another within the medium. Without a medium, mechanical waves cannot travel.
A mechanical wave, such as a sound wave or water wave, requires a medium (substance) to travel through. In a mechanical wave, the energy is transferred through the medium by the vibration of particles.
Mechanical waves, such as sound waves, require a medium to travel through. These waves propagate by causing particles in the medium to vibrate and transfer the energy of the wave. Electromagnetic waves, such as light waves, do not require a medium and can travel through a vacuum.
Mechanical waves must travel through a medium, such as solid, liquid, or gas. These waves transfer energy by causing particles in the medium to vibrate back and forth in the direction of wave propagation.
No. Light is an example of an electromagnetic wave, which can travel through a vacuum. Mechanical waves must travel through a medium, and cannot travel through a vacuum.
Mechanical waves need a medium substance to travel through. Electromagnetic do not.
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.

Mechanical waves need a medium to travel through, such as air, water, or solids. These waves propagate by transferring energy from one particle to another within the medium. Without a medium, mechanical waves cannot travel.
Mechanical waves are waves that require a medium in which to travel, i.e., a solid or fluid. As sound needs a medium to travel, sound is a mechanical wave.
Yes, mechanical waves require a medium to travel through. This is because mechanical waves transfer energy by causing particles in the medium to vibrate back and forth in the direction of the wave. Examples of mechanical waves include sound waves and seismic waves.
