Questions & Step-by-Step Solutions
A tuning fork produces a sound wave with a frequency of 440 Hz. What is the wavelength of the sound wave in air, given that the speed of sound in air is approximately 340 m/s?
Step 1: Identify the formula for wavelength, which is λ = v/f, where λ is the wavelength, v is the speed of sound, and f is the frequency.
Step 2: Write down the values you have: the speed of sound in air (v) is 340 m/s and the frequency (f) is 440 Hz.
Step 3: Substitute the values into the formula: λ = 340 m/s / 440 Hz.
Step 4: Perform the division: 340 divided by 440 equals approximately 0.7727 m.
Step 5: Round the result to two decimal places: 0.7727 m is approximately 0.77 m.
Wave Properties – Understanding the relationship between frequency, wavelength, and speed of sound in a medium.
Formula Application – Applying the formula λ = v/f correctly to calculate wavelength.
