Given:
Distance from earth to moon (D)= 3.84*10⁵ km
Frequency of radio wave = 7.25*10⁵ Hz
To determine:
Time taken (T) for the radio wave to travel from earth to moon
Explanation:
The speed at which the radio wave travels = speed of light c = 3.0 *10⁸ m/s
Speed = Distance traveled/time take
Time taken = Distance/Speed = 3.84*10⁸ m/3.0*10⁸ ms-1
Time = 1.28 sec
Ans: The time taken will be 1.28 sec and is independent of the frequency
