A marine distress beacon transmitter operates at a radio frequency of 150 MHz.
To maximize its transmission range, the beacon is equipped with a half-wave dipole antenna, which requires an antenna length equal to exactly one-half of the wavelength of the transmitted waves.
Calculate the required length of this dipole antenna.
The speed of the radio waves in air is 3.00 × 108 m/s.
