Explanation:
The range of an AM broadcast depends on two main factors - antenna power and carrier frequency.
Antenna Power:
The power of the transmitting antenna determines the strength of the signal that is radiated into space. A higher power antenna will emit a stronger signal which can travel further before being attenuated by the atmosphere.
Carrier Frequency:
The carrier frequency of an AM broadcast is the frequency at which the signal is transmitted. The range of an AM broadcast depends on the frequency of the carrier wave. Higher frequency signals have shorter wavelengths and are more easily absorbed by the atmosphere, limiting their range. Lower frequency signals have longer wavelengths and can travel further before being absorbed.
Conclusion:
In summary, the range of an AM broadcast depends on both the antenna power and carrier frequency. A higher power antenna and lower carrier frequency will result in a longer range for the broadcast signal.
