A transverse wave is represented by the equation y = y_(0) sin " "(2pi)/(lambda) (vt- x) For what value of lambda is the particle velocity?

Answer»

`lambda = pi y_(0)`
`lambda = pi y_(0) l^(2) `
`lambda = xy_(0)l^(3)`
`lambda = 2 pi y_(0)`.

Solution :y = `y_(0)sin (2pi)(lambda) (V t - x)`
here `V_(MAX) = 2V`
`y_(0) OMEGA = 2v`
`y_(0).2 pi v"" rArr "" (v)/(V) = pi y_(0)`.
or `"" lambda = pi y_(0)`
CORRECT choice is (a).
