A sinusoidal wave is propagating in negative x -direction in a string stretched along x-axis. A particle of string at is found at its mean position and it is moving in positive y-direction at . The amplitude of the wave, the wavelength and the angular frequency of the wave are 0.1 meter, meter and respectively. The equation of the wave is
detailed solution
Correct option is C
The equation of wave moving in negative x -direction, assuming origin of position at x=2 and origin of time (i.e. initial time) at t=1sec . y=0.1sin(2πt+4x) Shifting the origin of position to left by 2 m , that is, to x=0 . Also shifting the origin of time backwards by 1 sec , that is to t=0sec . y=0.1sin(2π(t−1)+4(x−2))Talk to our academic expert!
