If you want to tune into a radio station that is carried by a signal with wavelength 3.0 meters, what channel would you choose?
Over [174]

Answer:  The radio should be tuned to 100. 0 Mhz.

Explanation:

As radio waves are electromagnetic waves, like x-rays, UV rays, and all the wavelengths of visible light, they propagate in the free space at the speed of light: 3. 10⁸ m/s.

At any wave, there is a fixed relationship between the distance travelled by the wave along one cycle (which is called wavelength ) and the speed at which the wave oscillates (which is called the frequency of the wave), with the speed at which the wave propagates, as follows:

λ (wavelength) =  v (speed) / f (frequency)

Replacing by the values, and solving for frequency, we have:

f = 3. 10⁸ m/seg / 3 m = 10⁸ 1/sec = 10⁸ Hz = 100. 0 Mhz

This is the radio channel to which must be tuned in order to listen the station with a wavelength of 3 m, in the FM band.

public boolean comesBefore(Episode e){

//Check if titles' match

//Compare season numbers

if(this.seasonNumber<e.seasonNumber){

return true;

}

else if(this.seasonNumber==e.getSeasonNumber()){

return this.episodeNumber<e.getEpisodeNumber();

}

}

atOverride // replace the at with at symbol

public String toString() {

return title+", season "+seasonNumber+", episode "+episodeNumber;

}

}

class Main{

public static void main(String[] args) {

Episode e = new Episode("Friends",1,1);

System.out.println(e);

Episode e2 = new Episode("The Wire",3,5);

System.out.println(e2);

System.out.println(e.getTitle()+" comes before "+e2.getTitle()+" = "+e.comesBefore(e2));

}

}
