Question
The exepression y = a sin bx sin ω trepre4senrs a stationary wave. The distance between the consecutive nodes is equal to :
Options
A.π / b
B.2π / b
C.π / 2b
D.1 / b
Solution
y = a sin bx sin ωt
on comparing with standard eqution of stationary wave
y = R sin
. sin ωt we ge
= bx,
∴ λ =
The distance between consveructive nodes
