A progressive wave of frequency $50 Hz$ is travelling with velocity $350 m / s$ through a medium. The change in phase at a given time interval of $0.01 s$ is

Options:

Answer:

Solution:

We know, $λ f = v$ $∴ λ = \frac{350}{50} = 7 m$ Path difference $x =$ Velocity $\times$ time $= 350 \times 0.01 = 3.5 m$ Phase change $\frac{2 π x}{λ} = \frac{2 π}{7} \times 3.5 = π$ radian
