A wave has a frequency of 5.0 Hz and a wavelength of 2.0 m. What is its speed?
Answer and explanation
Correct answer: A. 10 m/s, from v = f x wavelength
- Step 1: The wave equation is v = f x wavelength. Step 2. 5.0 x 2.0 = 10. Answer: 10 m/s. Why not the others: the others divide or add unlike quantities.
