AP Physics 2 Exam Question:

A sound wave with a frequency of 1000 Hz travels through air at a speed of 343 m/s. Calculate the wavelength of the sound wave.

AP Physics 2 Exam Answer:

We can use the formula v = f * λ, where v is the speed of sound, f is the frequency, and λ is the wavelength.

Given that the frequency f = 1000 Hz and the speed of sound v = 343 m/s, we can rearrange the formula to solve for the wavelength, λ:

λ = v / f = 343 m/s / 1000 Hz ≈ 0.343 m

Therefore, the wavelength of the sound wave is approximately 0.343 meters.
