Question

A radio announcer's voice is transmitted via radio waves a distance of 603.32 km. How much time, in microseconds, will it take to transmit the wave over this distance?

Answer 1

Given:

The distance traveled by radio waves is d = 603.32 km

Required: The time taken to transmit the wave over this distance.

Step-by-step explanation:

The time taken to transmit the wave can be calculated by the formula

`t=(d)/(c)`

Here, c is the speed of the wave whose value is

`c=3*10^8\text{ m/s}`

On substituting the values, the time taken by the wave will be

`\begin{gathered} t=\frac{603.32*1000\text{ m}}{3*10^8\text{ m/s}} \\ =2011.067\text{ }\mu s \end{gathered}`

Final Answer: The time taken to transmit the distance by the wave is 2011.067 microseconds.
