If a radio wave has a period of 1 μs what is the wave's period in seconds

Period of wave is defined by the time taken to complete one cycle of the wave i.e. from one crest to one trough.

Since, the period of the wave is already given in microseconds, we just have to convert into seconds.

we know

Therefore, the period of wave would be .

Taking into account the conversion of units, the wave's period is 1×10⁻⁶ s.

First of all, it is necessary to know that the period is the time it takes for a periodic phenomenon to repeat itself. In other words, it is the time that elapses between the emission of two consecutive waves, that is, the time it takes for a complete wave to pass through a reference point.

In the International System of Units the period is measured in seconds.

The period of the wave is expressed in microseconds and you want to express it in units of seconds. For that you must know that 1 μs is equivalent to 1×10⁻⁶ s.

In summary, the wave's period is 1×10⁻⁶ s.
