Question

Х
17) Phase difference =
path difference.​

Answer 1

Answer:

phase difference = 2pi/lamda × path difference

Explanation:

y1= ysin(wt + kx1 )

y2=ysin(wt +kx2)

phase difference = (wt +kx2) - (wt+kx1)

= k(x2-x1)

=2pi/lamda (x2-x1)

phase difference =(2pi/lamda) × path difference

hope you understand.
