A wave has a frequency of 50 Hz and a wavelength of 2 m. What is the speed of the wave?
Show the answer and explanation
Correct answer
C. 100 m/s
Principle or equation
Wave speed v = f * λ.
Why this answer is correct
v = 50 Hz * 2 m = 100 m/s.
Example
A wave with frequency 10 Hz and wavelength 3 m travels at 30 m/s.
