6. Why does sound travel faster through a steel bar than through a swimming pool filled with water? Water is a denser medium than steel.
Water has a larger wavelength than steel.
Steel has a larger wavelength than water.
Steel is a denser medium than water.

I understand that sound travels faster in water then in air. Water is a liquid, and air is gas.

Water still has the ability to roll the molecules over each other (so water can flow), it has some flexibility.

But I do not understand how a solid that is inflexible can make sound waves travel faster then in a flexible liquid.

In fact, sound waves travel over 17 times faster through steel than through air.

Sound waves travel over four times faster in water than it would in air.

As newton's first law states a object in motion stays in motion
