Reflected Wave Equation
A wave traveling along positive X-axis is given by y = A sin (ωt – kx). If it is reflected from rigid boundary such that 80% amplitude is reflected, then equation of reflected wave is
SELECT ONE OPTION

B
Y = -0.8A sin (ωt + kx)
C
Y = 0.8A sin (ωt + kx)
D
Y = A sin (ωt + 0.8kx)
