A) 8 cm
B) 25 cm
C) 50 cm
D) 100 cm
Correct Answer: A
Solution :
The standard equation of a wave of amplitude a is given by \[y=a\,\sin \,2\pi \,\left( \frac{x}{\lambda }-\frac{t}{T} \right)\] ... (i) Given, equation is \[y=8\,\,\sin \,2\pi \,(0.01x-2\,\omega \,t)\] ... (ii) Comparing Eqs. (i) and (ii), we get a = 8 cmYou need to login to perform this action.
