Question: A sound wave travels in air at a speed of 340 m/s. If the frequency of the sound wave is 1700 Hz, what is its wavelength?

Options:

Correct Answer: 0.5 m

Solution:

Wavelength λ = v/f = 340 m/s / 1700 Hz = 0.2 m.

A sound wave travels in air at a speed of 340 m/s. If the frequency of the sound wave is 1700 Hz, what is its wavelength?

A sound wave travels in air at a speed of 340 m/s. If the frequency of the sound wave is 1700 Hz, what is its wavelength?

Step 1: Understand the formula for wavelength, which is λ = v / f, where λ is the wavelength, v is the speed of the wave, and f is the frequency.
Step 2: Identify the values given in the question: the speed of the sound wave (v) is 340 m/s and the frequency (f) is 1700 Hz.
Step 3: Plug the values into the formula: λ = 340 m/s / 1700 Hz.
Step 4: Perform the division: 340 divided by 1700 equals 0.2.
Step 5: Conclude that the wavelength (λ) is 0.2 meters.

Wave Properties – The relationship between speed, frequency, and wavelength of a wave, described by the formula λ = v/f.
