A wave given xi = 10 sin[(80pit - 4pix)]...

A wave given `xi = 10 sin[(80pit - 4pix)]` propagates in a wire of length `1m` fixed at both ends. If another wave is superimposed on this wave to produce a stationary wave then

A

the superimposed wave is `xi = 10 sin [80pit + 4pix]`

B

the amplitude of the stationary wave is `20 m`.

C

the wave length of the wave is `0.5 m`.

D

the number of total nodes produced in the wire are `3`.
