Aug 13, 2022 · Let us now look at the three mediums that sound can travel through, solids, liquids, and gases, and how they change the reaction of the sound. Gases. First up we can look at gasses. You might wonder why gasses are mentioned when speaking of mediums that sound can move in.
sound can travel through solids, liquids and gases; sound cannot travel through a vacuum – it needs a medium to travel through; the speed of sound in air is approximately 340 m/s
This explains why sound travels faster through hotter air compared to colder air. The speed of sound at 20 degrees Celsius is about 343 meters per second, but the speed of sound at zero degrees Celsius is only about 331 meters per second.

- When a sound wave meets a change in medium, it splits. Some of it goes through, some is reflected back. Your brain is weird sometimes. If you hear...
- As the humidity increases, the speed of sound will increase.
- They are totally different types of waves. There's no reason to expect an electromagnetic wave that requires no medium to behave the same as a mech...
- The speed depends on both pressure AND density but the effects cancel out, and for an ideal gas you cannot increase pressure without also increasin...
- Some of it gets reflected just like how when a water wave reaches land some of the water gets reflected back to the center of the waves. So you mig...
- This has more to do with the interaction of macroscopic mechanical properties of the material being considered. Sound waves propogate via vibration...
- It's not Newton- Laplace equation .its only Newtons equation because Newton Laplace equation has a "gamma" in the numerator called Adiabatic elasti...
- It's not only density. It also can involve a metric called the bulk modulus, which is related to density, for a gas. And for a solid or liquid it a...
- an iron girder is rigid because it is difficult to bend. rigid is opposite to flexible gold is dense because it has a lot of mass in a small volume

Mar 17, 2021 · Explain that sound can move through solids, liquids and gases. Describe how sound needs molecules to move and that changing the medium that it travels through changes the sound. Describe how engineers use sound energy when designing spaces, such as movie theaters.
