Why will sound of low frequencies travel farther in air than sound of high frequencies?

The answer to this question has to do with the nature of waves. A high frequency sound has a greater wavelength than a low frequency sound. A high pitched noise wave looks a bit like NNNNNNNN, whereas a low sound looks a bit more like _____. Because the high pitched noise has a "taller" wave, so to speak, it is more easily interrupted, and cannot, therefore, travel as far as a low sound.

sounds with higher frequency have more energy and the energy decreases along with distance and so is the frequency........so a sound with high frequency can travel farther due to its more amplitude,wavelength and intensity.

The above is in error. A high frq. sound has a shorter (time is the abcissa(x) axis) wavelength than a lower freq. sound. Tallness or amplitude is not to be confused with wavelength. Amplitude is normally the ordinate or y axis and is a measure of magnitude. Energy content is a factor of both wavelength and amplitude. Lower frequency waves commonly travel better through matter as a result of the atomic spacing of the molecules in the medium( air, solid matter etc.). i.e. Think of dominoes falling.
