Final answer:
The frequency of an AM radio transmitter can be converted from kilohertz (kHz) to megahertz (MHz) by dividing the value by 1000. In this case, a frequency of 1050 kHz is equal to 1.05 MHz.
Step-by-step explanation:
The frequency of an AM radio transmitter is typically measured in kilohertz (kHz). To convert this frequency to megahertz (MHz), divide the value by 1000. So, for example, a frequency of 540 kHz would be equivalent to 0.54 MHz.
Therefore, in this case, a frequency of 1050 kHz would be equal to 1.05 MHz when converted to megahertz.
