Speed of Sound
1. What is the Speed of Sound in MPH?
The Speed of Sound in mph is 767mph.
2. What is the Speed of Sound in Kilometers per Hour?
The Speed of Sound Kilometers per Hour is 1,235 kmph.
3. How Fast does Sound Travel per Second?
As the speed of Sound is 1236 km/h at 20°C in air, thus per second sound travels 1236/3600 ≈ 0.343 Kilometers or 343.33 meters.
4. What is the Formula for Speed of Sound?
The formula for speed of sound is wavelength/time or wavelength × frequency.
5. In which medium, Sound travel fastest?
Sound travels fastest in Solid.
6. What is the Nature of Sound Wave?
Sound Wave is a mechanical wave and is longitudinal in nature.
7. What are the Factors on which the Speed of Sound Wave depends?
Speed of Sound Wave depends on the density and the temperature of the medium.
8. How does the Speed of Sound depend on the Density of the Medium?
The Speed of Sound increases with an increase in the density of the material.
9. How does the Speed of Sound depend on the Temperature of the Medium?
The speed of sound is directly proportional to the temperature of the material.
10. What is the Speed of Sound in Vacuum?
The speed of sound in vacuum is 0 because there is an absence of matter.
11. How does the Speed of Sound depend on the Elasticity of the Medium?
The Speed of Sound is directly proportional to the square root of the elasticity of the material. It is given as v √(B/ρ) where B is the Bulk Modulus of Elasticity and ρ is the density of the material.
Speed of Sound
Speed of Sound as the name suggests is the speed of the sound in any medium. We know that sound is a form of energy that is caused due to the vibration of the particles and sound travels in the form of waves. A wave is a vibratory disturbance that transfers energy from one point to another point without the actual transfer of matter. Hence, when we speak the sound from our vocal cords reaches to listener’s ear in the form of a wave.
Since the sound travels from the source point to the destination point within a time period, this encourages us to calculate the speed of the sound with which it travels. Also, we know that Sound is a mechanical wave hence its speed of propagation varies in different materials. In this article, we will learn, what is sound, what is the definition of Speed of Sound and the Speed of Sound with which it propagates in different media.
