Question

two sound waves are Y is equal to a Sin Omega T minus and Y is equal to a cos Omega T minus kx phase difference between them is

Answer 1

Answer:

Explanation:

so  y=sin(wt-KX)

is the first equation

and y=cos(wt-kx)is the second equation hence

we can write y=sin(wt-kx+90)

so the phase diff between 2 wave is 90
