WebAt normal atmospheric pressure, the temperature dependence of the speed of a sound wave through dry air is approximated by the following equation: v = 331 m/s + (0.6 m/s/C)•T … Web60 cm/s change of speed of sound. That gives e.g. at ϑ = 20°C the speed of sound c = 331.3 + 0.606 × 20 = 343.42 m/s. Often the easy calculation will do: c ≈ 331 + (0.6 × 20) = 343 m/s. 1°C change of temperature is equal to 60 cm/s change of speed of sound. There is a useful formula (rule of thumb) to get the temperature ϑ (°C)

WebIt is inversely proportional to the frequency of the wave if we assume that the wave is moving at a fixed speed. At 20 °C or 68 °F, the sound is traveling in dry air at about 343 meters per second or 1125 feet per second or a 1 kilometer per approximately 3 seconds. It travels faster in liquids and even faster in solids. For example, the ...

17.3: Speed of Sound - Physics LibreTexts

WebWe can find the speed of sound by looking at the speed of this compressed region as it travels through the medium. In non-humid air at 20 degrees Celsius, the speed of sound is … WebThis 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. Remember, the only way to change the speed of sound is to change the properties of the medium it's ... WebThe speed of sound increases by 0.6 meters per second (m/s) for every degree-Celsius (°C) increase in temperature. Since the speed of sound is about 331.5 m/s at 0 °C, we can use … read aloud little cloud
