Question

The speed of a wave in a medium is 760 m/s. If 3600 waves are passing through a point, in the medium in 2 minutes, then its wavelength is: (A) 13.8 m (B) 25.3 m (C) 41.5 m (D) 57.2 m

Tardigrade Admin · Accepted Answer

We use frequency of wave is n=(3600/2 × 60) Hz ⇒ λ=(v/n)=(760/30)=25.3 m .

Q. The speed of a wave in a medium is $760 m / s .$ If $3600$ waves are passing through a point, in the medium in $2$ minutes, then its wavelength is:

13.8 m

25.3 m

41.5 m

57.2 m

We use frequency of wave is
$n = \frac{3600}{2 \times 60} Hz$
$\Rightarrow λ = \frac{v}{n} = \frac{760}{30} = 25.3 m .$
