The principals of SONAR is that transmitter sends a sound signal which bounces backwards from the object to receiver.
hence, as far as i understand there should not be any difference which freuqency to use.
or it is a matter of diffraction of sound wave, like if wavelength is too long then small objects will be covered by the wave and will not reflect?
what influence and why have different frequencies for sonar?
thank you.
