The speed of electromagnetic waves is similar to the speed of light.
As Wheat finished this sentence,
Faraday was taken aback, then suddenly slapped his forehead with a crisp "pop".
So that's it...
No wonder this number had seemed familiar to him.
2.97969X10^8m/s—doesn't that practically match the previously calculated speed of light?!
But...
Why is that?
You have to know:
In this era, the scientific community already has a fairly clear understanding of mechanical waves:
They are caused by the propagation of disturbances, resulting in the transfer of momentum and energy within matter.
At the same time, mechanical waves can be divided into two types: longitudinal and transverse.
For example, waves along a string and sound waves, and of course mixed waves as well.
Besides the differences in type, the speed at which waves propagate varies as well.
For instance, the speed of sound is 340 meters per second, measured by Dehan, a Brit.
