Sound waves are invisible and can move through the water, therefore the correct answer is option D.

What is a sound wave?

It is a particular variety of mechanical waves made up of the disruption brought on by the movements of the energy. In an elastic medium like the air, a sound wave travels through compression and rarefaction.

Sound waves cannot travel in a vacuum, and they are invisible in nature.

While electromagnetic waves are transverse waves, sound waves are longitudinal waves, and the temperature of the medium in which they travel greatly affects the speed of the sound.

The mathematical expression for the speed of the sound in air is given by

v= √γRT

where v is the speed of the sound

R is the ideal gas constant

T is the temperature

γ is the adiabatic index

The speed of sound in air at 0° Celcius is 330 m/s.

Since sound waves can travel through water and are invisible, option D is the appropriate answer.
