A) 20 cm
B) 40 cm
C) 60 cm
D) none of these
Correct Answer: B
Solution :
The equation of transverse wave is \[y=5\sin 2\pi \left[ \frac{t}{0.04}-\frac{x}{40} \right]\] ??.(i) Now standard equation of transverse wave is \[y=a\,\sin 2\pi \left[ \frac{t}{T}-\frac{x}{\lambda } \right]\] ??(ii) Comparing equations (i) and (ii), we get \[\frac{x}{\lambda }=\frac{x}{40}\] or \[\lambda =40cm\]You need to login to perform this action.
