A sound wave travels through air at 340 m/s with a frequency of 170 Hz. What is its wavelength?
Answer and explanation
Correct answer: B. 2.0 meters
- Step 1: v = f lambda => lambda = v / f. Step 2. lambda = 340 / 170 = 2.0 meters. Answer: 2.0 meters. Why not the others:* 0.5 divides frequency by velocity.
