A wave has frequency 50 Hz and speed 340 m/s. What is its wavelength?
Answer and explanation
Correct answer: B. 6.8 m, from 340 / 50
- Step 1: Wavelength = speed / frequency. Step 2. 340 / 50 = 6.8 m. Answer: 6.8 m. Why not the others: Inverting or multiplying the two numbers does not give a length.
