The mind-bending concept of time dilation results from a seemingly harmless assumption—that the speed of light is the same ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

Radar uses radio waves which are electromagnetic waves and travel at a speed of 300,000,000 m/s. Distance = speed x time. Speed = 300,000,000 m/s.

The speed of light and all of the electromagnetic spectrum in a vacuum is 300,000,000 m/s or 3×10 8 m/s. The speed of sound in air is often taken to be 340 m/s, but this can vary depending on ...
