An observer is moving with half the speed of light towards a stationary microwave source emitting waves at frequency 10 GHz. What is the frequency of the microwave measured by the observer ? (Speed of light =3xx10^(8)ms^(-1)) |

Answer» `17.3` GHz `=fxxx sqrt((1+(1)/(2))/(1-(1)/(2))) "" [ :. beta=(v)/(c)=(1)/(2)]` `=fsxxsqrt(((3)/(2))/((1)/2))` `=10 xx sqrt(3)` `=10xx1.73` `=17.3 GHz` |
