A) 1000
B) 300
C) 180
D) 2000
Correct Answer: A
Solution :
Wavelength \[(\lambda )\] is defined as the distance between repeating units of a wave pattern. Also, velocity \[=\frac{distance\,\,\left( d \right)}{time\,\,(t)}\] Given, d = 600 m, t = 2 s \[\therefore \] \[v=\frac{600}{2}=300\,m/s\], \[f=500\,Hz\] From equation \[v=f\lambda \], we have \[\lambda =\frac{v}{f}=\frac{300}{500}=\frac{3}{5}m\] Number of waves in 600 m \[=\frac{600}{3/5}=1000\].You need to login to perform this action.
