JEE Mains · Physics · STD 11 - 14. waves and sound
A travelling wave is described by the equation \(y(x, t)=[0.05 \sin (8 x-4 t] \;m\) The velocity of the wave is \(.....ms ^{-1}\) [all the quantities are in SI unit]
- A \(4\)
- B \(2\)
- C \(0.5\)
- D \(8\)
Answer & Solution
Correct Answer
(C) \(0.5\)
Step-by-step Solution
Detailed explanation
From the given equation \(k =8\,m ^{-1}\) and \(\omega=4\,rad / s\) Velocity of wave \(=\frac{\omega}{ k }\) \(v =\frac{4}{8}=0.5\,m / s\)
