A body vibrating with time period of 2 milliseconds produces a wave travelling in a mdium with velocity of 1250m/s. Calculate the wavelength ?

Solution

Velocity v $=$ 1250m $/$ s
Time period T $=$ 2 milliseconds $=$ 2 $/$ 1000 sec
Velocity (v ) $=$ wavelength( $λ$ ) $\times$ frequency (f)
Velocity (v ) $=$ wavelength( $λ$ ) $\times$ 1 $/$ Time period
1250 $=$ $λ$ $/$ (2 $/$ 1000)
$λ$ $=$ 1250 $\times$ 2 $/$ 1000 $=$ 2 $\cdot$ 5m

Velocity v =1250m/s Time period T = 2 milliseconds =2/1000 sec Velocity (v )= wavelength( λ) × frequency (f) ​Velocity (v )= wavelength( λ) × 1/ Time period ​1250 = λ / (2/1000) λ = 1250×2/1000 = 2·5m
