Low frequency sound waves, such as infrasound and low-frequency ultrasound, travel furthest through water because they have longer wavelengths and can penetrate water with less energy loss. High frequency sounds are absorbed more quickly by water due to their shorter wavelengths.

Sound travels furthest through solids because the particles in a solid are packed closely together, allowing for easier transfer of sound waves. Air is the least efficient medium for sound to travel through.
Electromagnetic waves of very low frequencies (such as ELF and SLF waves) cannot travel through air or water as they are absorbed or reflected.
Water waves are mechanical waves that require a medium (water) to propagate, while electromagnetic waves are a form of energy that can travel through a vacuum. Water waves exhibit transverse motion, while electromagnetic waves have electric and magnetic fields oscillating perpendicular to each other and the direction of wave propagation. Additionally, water waves have lower frequencies and wavelengths compared to electromagnetic waves.
Yes, electricity can travel through water because water is a conductor of electricity due to the presence of ions.
Sonar frequencies typically range from around 20 kHz to several hundred kHz. Lower frequencies can travel long distances in water, but higher frequencies provide better resolution for detailed imaging. The choice of frequency depends on the specific application and environmental conditions.
