The speed of a wave in a certain medium is $960 m / s$ . If 900 waves pass over a certain point of the medium in half a minute, the wavelength of the wave is

Options:

Answer:

Solution:

$v = 960 m / s λ = ?$ 900 waves passes in $30 sec$ . $∴ 30$ waves passes in $1 sec$ $∴ v = 30$ $∴ λ = \frac{v}{v} = \frac{960}{30} = 32 m$
