Two 1 MHz radio antennas emitting in-phase are separated by600
algol [13]

Answer:

1 km

Explanation:

d_0 = Gap between antennas = 600 m

\nu = Frequency = 1 MHz

z_1 = Distance to receiver = 2 km

c = Speed of light = 3\times 10^8\ m/s

Wavelength is given by

\lambda=\dfrac{c}{\nu}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{1\times 10^6}\\\Rightarrow \lambda=300\ m

Distance to be moved is given by

D=\dfrac{z_1\lambda_0}{d_0}\\\Rightarrow D=\dfrac{2\times 300}{600}\\\Rightarrow D=1\ km

The distance to be moved is 1 km north.
