Question

The speed of a wave in a certain medium is 960 m/sec. If 3600 waves pass over a certain point of the medium in 1 minute, the wavelength is

• A. 2 meters
• B. 4 meters
• C. 8 meters
• D. 16 meters

Answer 1

Answer: (D)

16 meters

Answer 2

v = 960 m/s ; n = $\frac{3600}{60}Hz$. So $\lambda = \frac{v}{n} = \frac{960}{60} =$16 meters.
