Question

A sine wave is travelling in a medium. The minimum distance between the two particles always having same speed speed, is

• A. $\frac{\lambda }{4}$
• B. $\frac{\lambda }{3}$
• C. $\frac{\lambda }{2}$
• D. $\lambda$

Answer 1

The correct option is C $\frac{\lambda }{2}$

The particle having same speed means they are in the same phase so continuous two-crust or trough are in the same phase so minimum distance between particle is $\frac{\lambda }{2}$
