. The displacement of a particle in a medium due to a wave traveling in the x-direction

through the medium is given by y = A sin (at - bx), where t = time, and a and b are constants. Which of the following is wrong.  

A. The frequency of the wave is a

B. The frequency of the wave is a/(2p)

C. The wavelength is (2p)/b

D. The velocity of the wave is a/b

Best Answer

Ans: A

Sol: Wave equation is, y = A sin (at - bx), compare it from y = A sin (wt – kx)
