AM is long wave, medium wave and short wave
remember this phenomenon when our zacs tried to catch BBC - c&p: During day time, AM signals usually travels or moved by groundwave, which diffract around the curve of the earth covering a distance up to a few hundred miles from the signal transmitter. However, during nighttime, changes in the ionosphere causes or makes AM signals to move by skywave that enables AM radio stations to be heard much farther from their point of origin than is normal during the day. This results many broadcast stations to minimize their broadcasting power up to certain extent during nighttime or even to suspend broadcasting entirely during nighttime hours.
