Question

If a carrier wave of 1000 kHz is used to carry the signal, the length of transmitting antenna will be equal to-

  1. 3 m    
  2. 30 m    
  3. 300 m    
  4. 3000 m    

The correct answer is: 300 m


    h equals lambda equals fraction numerator c over denominator v end fraction equals 3 cross times 10 to the power of 8 end exponent divided by 10 to the power of 5 end exponent equals 300 m
