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
What else can I help you with?
What does mechanical wave needs to travel?
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.
What is a wave that requires a medium wave?
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.
What waves need a medium to travel in?
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.
What do Mechanical waves must travel through?
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.
Is light an example of mechanical wave?
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.
What needs a medium substance to travel through?
Mechanical waves need a medium substance to travel through. Electromagnetic do not.
How mechanical and electromagnetic wave are different?
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
What can travel only through a medium?
mechanical waves
What can a mechanical waves travel through?
A medium which is air
Which of the following distinguishes electromagnetic from mechanical waves?
They don't require a medium to travel through. - apex ....what a wanker
What does mechanical wave needs to travel?
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.
Why are sound waves not considered a mechanical wave?
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.
Due mechanical waves need a medium to travel through?
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.
How do you know the wave is mechanical?
It requires a medium through which to travel
A mechanical wave can travel only through what?
A medium which is air
What is a wave that requires a medium wave?
