The contemporary value for the speed of sound in dry air at a temperature of 0 ☌ (32 ☏) is 331.29 meters (1,086.9 feet) per second.The speed of "sound" is actually the rate at which a minor disturbance is transmitted across a medium.Time = 1500 meters / 700 meters per second = 2.1 seconds SUMMARY We get this by substituting the numbers in the equation. The time it takes a sound wave to traverse 1.5 kilometers can be calculated as follows: We get by substituting the numbers in the equation. We know that the formula for calculating sound speed is: How long does a sound wave with a frequency of 2 kHz and a wavelength of 35 cm take to traverse 1.5 kilometers? The quantity of waves that pass a location per unit of time has the same frequency as the source. The distance between neighboring compressions or rarefactions determines the wavelength of a sound. Where v denotes velocity, λ denotes sound wave wavelength, and f denotes frequency.įor all waves, the relationship between the speed of sound, its frequency, and wavelength is the same. SPEED OF SOUND FORMULAīecause the speed of sound is defined as the distance traveled by a sound wave in a given amount of time, it can be calculated using the following formula: As a result, the speed of sound increases as the temperature rises. The temperature has a direct relationship with the speed of sound. As a result, as the density of the medium increases, so does the speed of sound. When the medium is dense, the molecules are packed tightly together, allowing sound to travel faster. The speed of sound is affected by the density and temperature of the material through which it travels. ![]() Sound travels at approximately 12,000 m/s through a very hard solid like a diamond, nearly 35 times its speed in air and the fastest it can travel under normal conditions.While sound travels at 343 meters per second in air, it travels at 1,481 meters per second in water (almost 4.3 times faster) and 5,120 meters per second in iron (almost 15 times as fast).Gases are the slowest, liquids are faster, and solids are the fastest.Sound travels at different speeds in different substances.Sound’s speed in colloquial speech refers to the speed of sound waves in the air.The contemporary value for the speed of sound in dry air at a temperature of 0 ☌ (32 ☏) is 331.29 meters (1,086.9 feet) per second. Sound speed is the rate at which sound waves travel through various materials.
