Wave equations of two particles is given by $y_{1} = a s i n (ω t - k x), a n d y_{2} = a s i n (k x + ω t)$ , then

Question

Q. Two waves are represented by the equations

y_{1} = a s i n (ω t + k x + 0.57) m

and

y_{2} = a c o s (ω t + k x) m

,
Where

x

is in meters and

t

is in seconds. The phase difference between them is then

Answer 1

The two particles are moving is opposite direction.

Wave equations of two particles is given by y1=asin(ωt−kx),andy2=asin(kx+ωt), then
