Is it true that X-band RADAR and Ka-band RADAR transmit signals at different speeds?

Both X-band RADAR and Ka-band RADAR operate under the principle of using electromagnetic waves to detect objects, and they both transmit signals at the speed of light, which is approximately 299,792 kilometers per second in a vacuum. This speed remains consistent regardless of the frequency band the RADAR operates in.

While X-band and Ka-band RADAR systems may differ in their frequencies and wavelengths, these factors do not affect the speed at which the signals travel through space. The difference in band specifications pertains more to the characteristics of the signals, such as resolution and range, rather than how fast they travel. Therefore, the assertion that they transmit signals at different speeds is not accurate, making the correct answer clear.
