Describe the effects of temperature on the speed of sound. Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength. You can observe direct evidence of the speed of sound while watching a fireworks display.
Speed of Sound Formula. Since the speed of sound is the distance travelled by the sound wave in a given time, the speed of sound can be determined by the following formula: v = λ f. Where v is the velocity, λ is the wavelength of the sound wave, and f is the frequency.
17 Ιουν 2023 · The speed of sound in dry air at room temperature is 343 m/s or 1125 ft/s. In physics, the speed of sound is the distance traveled per unit of time by a sound wave through a medium. It is highest for stiff solids and lowest for gases.
