Question

A constituent waves of a stationary wave have amplitude, frequency and velocity 8 cm, 30 Hz and 180 cm/s respectively . Write down the equation of the stationary wave.

Answer 1

the equation of stationery wave is given by
y= 2a sin 2πn ( t + x/ v )

hence,
y = 2( 0.08) sin 2π (30) (t+ x/ 1.80) m
