Question

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

• A. 2 m
• B. 4 m
• C. 8 m
• D. 16 m

Answer 1

The correct option is D

16 m

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

So $\lambda =\frac{v}{n}=\frac{960}{60}=16m$
