A) 300
B) 600
C) 1200
D) 200
Correct Answer: A
Solution :
If a wave equation is given, in order to determine the wave characteristics. We compare the given wave (or oscillation) with the general equation of wave. The given equation of wave \[y={{10}^{-4}}\sin \left( 600\,t-2x+\frac{\pi }{3} \right)\] ... (i) Standard equation of wave \[y=a\sin \,\,(\omega t-kx+\phi )\] ... (ii) Now, comparing Eqs. (i) and (ii), we get \[\omega =600\] and k = 2 \[\therefore \] Velocity of wave \[=\frac{\omega }{k}=\frac{600}{2}=300\,m/s\]You need to login to perform this action.
