Question

how long would it take a radiowave of frequency,6×10^3sec^-1 to travel from Mars to the earth,a distance of 8×10^7 km?
​

Answer 1

Answer:

Radio waves travel at the speed of light. So in this case distance = speed × time

Time =

3×10

8

ms

1

8×10

7

Km

= 266.66 sec

Time =

60

266.66

= 4.44 minutes

Answer 2

Explanation:

Radio waves travel at the speed of light. So in this case distance = speed × time

Time = 8×107Km /3×108ms = 266.66 sec

Time = 266.66/60

= 4.44 minutes
