1.	A transverse wave is represented by `y=Asin(omegat-kx)`. For what value of the wavelength is the wave velocity equal to the maximum particle velocity?A. `piA//2`B. `piA`C. `2piA`D. `A`
Answer» Correct Answer - C Wave velocity `v=(lamda)/(T)=(omegalamda)/(2pi)` Maximum particle velocity `(v_(max))_(rho)=Aomega` Given `v=(v_(max))_(rho)` `(omegalamda)/(2pi)=A omega rArr lambda=2piA`
