[Kerry] decided to use the tube to measure the speed of light. There are several common methods to indirectly measure the speed of light by relating frequency to wavelength (for example ...

Speed\((v)\) is in metres per second \(m\,s^{-1}\), distance \((d)\) in metres \((m)\) and time\( (t)\) in seconds \((s)\). Measuring the time taken for a sound wave ...
