* Speed of light: Both X-rays and microwaves are forms of electromagnetic radiation, which means they travel at the speed of light in a vacuum. That speed is approximately 299,792,458 meters per second.
* Frequency: X-rays and microwaves have different frequencies. X-rays have much higher frequencies than microwaves.
Therefore, in a vacuum, both X-rays and microwaves travel at the same speed (the speed of light).
The difference is in their frequency, which affects their properties:
* Higher frequency (like X-rays) means:
* More energy
* Shorter wavelength
* Can penetrate matter more easily
* Lower frequency (like microwaves) means:
* Less energy
* Longer wavelength
* Less penetrating power
In short, the speed is the same, but the properties due to their different frequencies are vastly different.
