1.	A longitudinal progressive wave is given by the equation y=5x10^(-2)sinpi(400t+x). The amplitude and wave length of the wave are (y,x are in m)
Answer» `A=5x10^(-2)m`, `lambda=2m` `A=5x10^(-2)m`, `lambda=3m` `A=5x10^(-2)m`, `lambda=4m` `A=5x10^(-2)m`, `lambda=5m` Solution :COMPARING with `y=Asin(omegat+kx)` `A=5xx10^(-2)m`, `K=pim^(-1)implieslambda=(2pi)/(K)`
