$A wave has a frequency of f = 50 Hz and a wavelength of λ = 2 m . What is the speed of the wave in m/s ?$

A. $25 m/s$
B. $50 m/s$
C. $100 m/s$
D. $200 m/s$

Show correct answer & step-by-step solution

Correct answer: C — $100 m/s$

Solution

The speed of a wave is calculated using the relation v = f λ . Substituting the given values, v = 50 \times 2 = 100 m/s .
