1.	The equation of a progressive wave is y=0.05sin(200t-(x)/(2))wherex,y are in metres and t in seconds then (a) velocity of wave is 100ms^(-1) (b) max velocity of particle is 10ms^(-1) (c ) wavelength of wave is 4m
Answer» only a and c are true only b and c are true only a and b are true a,b,c are true Solution :By comparing with `y=Asin(omegat-kx)` we GET `omega=200rad//sec`, `K=(1)/(2)m^(-1),A-0.05m` `(a) V=(omega)/(K) (b) (V_(rho))_(max)=Aomega` `(c ) lambda=(2pi)/(K)`
