Question

Problem 15.15 A sinusoidal wave has period 0.20 sand wavelength 2.5 m Part A What is the wave speed? Express your answer in meters per second. V AXO 2 Submit Request Answer

Answer 1

Answer : - The wave velocity is given as

• 
  --
  ................................................(1)
• where $\omega$ is the angular frequency and k is propogation constant .
• as we know that relation between angular frequency & time period is given by $\omega = \frac{2\pi}{T}$
• and the wave propogation constant is given as $k = \frac{2\pi}{\lambda }$
• so putting the above two value in equation (1) we get
• $v = \frac{\lambda}{T }$
• now putting the given values
• $v = \frac{2.5}{0.20 }$
