The wavelength of the sound wave is 2.8 cm. The time from the beginning to the end of the wave train is 2 seconds.Find the speed of the sound wave.
Question
The wavelength of the sound wave is 2.8 cm. The time from the beginning to the end of the wave train is 2 seconds.Find the speed of the sound wave.
Solution
To find the speed of the sound wave, we can use the formula:
Speed = Wavelength / Time
Given that the wavelength of the sound wave is 2.8 cm and the time from the beginning to the end of the wave train is 2 seconds, we can substitute these values into the formula:
Speed = 2.8 cm / 2 s
To calculate the speed, we need to convert the units to be consistent. Let's convert the wavelength from centimeters to meters:
Speed = 0.028 m / 2 s
Now we can divide the wavelength by the time to find the speed:
Speed = 0.028 m / 2 s = 0.014 m/s
Therefore, the speed of the sound wave is 0.014 m/s.
