Q
Q: A sound wave travels through air at a speed of 340 m/s. If its frequency is 1700 Hz, what is its wavelength? (2022)
Solution:
Wavelength (λ) = speed (v) / frequency (f) = 340 m/s / 1700 Hz = 0.2 m.
Steps: 6
Show Steps
Step 1: Identify the speed of the sound wave, which is given as 340 m/s.
Step 2: Identify the frequency of the sound wave, which is given as 1700 Hz.
Step 3: Use the formula for wavelength, which is Wavelength (λ) = speed (v) / frequency (f).
Step 4: Substitute the values into the formula: λ = 340 m/s / 1700 Hz.
Step 5: Perform the division: 340 divided by 1700 equals 0.2.
Step 6: Conclude that the wavelength (λ) is 0.2 meters.
