A radio wave sent into space strikes an asteroid and is reflected back to Earth 1 second after being emitted. How far away is the asteroid?
To find: the distance of asteroid from the earth when a radio wave strikes an asteroid and reflected the earth
Explanation of Solution
Introduction:
Radio waves have the longest wavelength in the electromagnetic spectrum, the waves which receive the electromagnetic radiation and converts into the mechanical vibrations.
Explanation:
A radio wave is sent to the asteroid from the earth and it reaches in a certain time (in seconds) and that radio wave reflected the earth
The speed of the reflected radio wave is the same as that of the incident wave ad so the time. Therefore, the distance from the earth to the asteroid is
Conclusion:
The radio wave has taken the time to reach the asteroid is
