The speed of a wave in a certain medium is 900 m/s. If 3000 waves passes over a certain point of the medium in 2 minutes, then compute its wavelength.

Explanation

The speed of a wave in medium `v=900ms^(-1)` Freq. of wave = no. of waves passing per
sec(n)`=3000"waves"//2"min"=(300)/(2xx60)=25s`
Wave length`=lambda=`?
`v= n lambda lambda=(v)/(n)`
`lambda=(900)/(25)=36m`
`lambda=36m`.
