Use of frequency from 530 kHz to 1700 kHz frequency range, there are also lower than this, which is called wavelength and wave with frequency higher than this, called short waves.
The frequency range from 530 kHz to 1700 kHz frequency range, there are less than this, which is called long wave, and waves with frequencies higher than this so-called short wave.
Use frequencies from 530 kHz to 1700 kHz also lower the frequency range, which is called long wave. และคลื่น with frequency higher than this is called Short wave.
