Higher frequencies tend to be more 'directional' than lower frequencies. Higher frequencies have a higher average power for any given section of the wave, than lower frequency waves. This doesn't mean they are 'louder' or have a higher peak amplitude it just means they have higher power.
Similarly one may ask, what is the difference between high and low frequency sound waves?
A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave. Amazingly, many people, especially those who have been musically trained, are capable of detecting a difference in frequency between two separate sounds that is as little as 2 Hz.
What is considered a low frequency?
Low frequency (low freq) or LF is the ITU designation for radio frequencies (RF) in the range of 30 kilohertz (kHz)–300 kHz. As its wavelengths range from ten kilometres to one kilometre, respectively, it is also known as the kilometre band or kilometre wave.
What is considered a high frequency?
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred metres).
