The equation of a stationary wave is y ...

The equation of a stationary wave is ` y = 0.8 cos ((pi x)/(20)) sin 200 pi t` where ` x` is in cm and t is in s. The separation between consecutive nodes will be

A

20cm

B

10cm

C

40cm

D

30cm

Text Solution

Verified by Experts

The correct Answer is:
A
`k=(pi)/(20)=(2pi)/(lamda) implieslamda=40cm` and the separation between consecutive nodes=`lamda/2=20cm`.
