Question: A sound wave travels through air at a speed of 340 m/s. What is the wavelength of a sound wave with a frequency of 1700 Hz? (2022)

Options:

Correct Answer: 0.2 m

Exam Year: 2022

Solution:

Using the formula λ = v/f, where v is the speed and f is the frequency, we have λ = 340 m/s / 1700 Hz = 0.2 m.

A sound wave travels through air at a speed of 340 m/s. What is the wavelength of a sound wave with a frequency of 1700 Hz? (2022)

A sound wave travels through air at a speed of 340 m/s. What is the wavelength of a sound wave with a frequency of 1700 Hz? (2022)

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 λ = v / f, where λ is the wavelength, v is the speed, and f is the frequency.
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 of the sound wave is 0.2 meters.

Wave Properties – Understanding the relationship between speed, frequency, and wavelength of sound waves.
Formula Application – Applying the formula λ = v/f correctly to calculate wavelength.
