An equation of a simple harmonic progressive wave is given by y=A (100 t-3 x) . The distance between two particles having a phase difference of ( 18 ) in meter is
Options
- A6
- B9
- C18
- D3
Correct answer
B. 9
Step-by-step solution
The correct option is (B). Concept: The phase difference given = ( 3 ) , so we can obtain the distance between two particles by using the path difference: k ( x ₂- x ₁ )= Where, k is the propagation constant. The general equation of the wave is given by y = A ( t - kx ) on comparing with the given equation, k =3 and =100 . Therefore, the distance between two particles is given by, ( x ₂- x ₁ )= k = 9 ~m
