How long would it take a radio wave of frequency `6xx10^(3) sec^(-1)` to travel from mars to the earth, a distance of `8xx10^(7)km` ?

Explanation

To solve the problem of how long it would take a radio wave of frequency \(6 \times 10^3 \, \text{sec}^{-1}\) to travel from Mars to Earth, a distance of \(8 \times 10^7 \, \text{km}\), we can follow these steps:

### Step 1: Understand the speed of radio waves
Radio waves travel at the speed of light, which is approximately:
\[ c = 3 \times 10^8 \, \text{m/s} \]
