the speed of light and all electromagnetic waves 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.

Those differed in their wave amplitude, wavelength ... “A way to get around this is to use the derived empirical equation, which can be inputted with conditions that are not tested.” ...

It is also the time taken for one whole wave to pass a point. Period is measured in seconds. All waves, including sound waves and electromagnetic waves, follow this equation. It should be noted ...
