Equation of progressive wave is given by y=4 sin( ( t5- x9)+ 6)wherey, x are in cm and t is in seconds. Then which ofthe following is correct?

Question

Accepted Answer

Correct answer: B. (b) The standard equation of a progressive wave is y=a sin [2 ( tT- x )+ ] The given equation can be written as y=4 sin [2 ( t10- x18 )+ 6 ] a=4 cm, T=10s , =18 cm and = /6.

$Equation of progressive wave is given by y = 4 sin (π (\frac{t}{5} - \frac{x}{9}) + \frac{π}{6}) wherey, x are in cm and t is in seconds. Then which ofthe following is correct?$
