A sine wave is travelling in a medium. A particular particle has zero

1.	A sine wave is travelling in a medium. A particular particle has zero displacements at a certain instant. The particle closest to it having zero displacements is at a distance(a) λ/4 (b) λ/3(c) λ/2(d) λ.
Answer» The correct answer is (c) λ/2 EXPLANATION: The particles at distance λ/2 have always the same displacement. So the closest zero displacement particle will be at λ/2 distance away.

Answer»

The correct answer is (c) λ/2

EXPLANATION:

The particles at distance λ/2 have always the same displacement. So the closest zero displacement particle will be at λ/2 distance away.
