After reflection from the open end a transverse progressive wave `y_1 =A sin 2pi (t//T-x//lambda ) ` travels along the direction of negative X-axis The equation of the reflected wave will be
A. `y^(2) =A sin 2pi (t//T-lambda //x)`
B. ` y^(2) =-A sin 2pi (t//T+x//lambda ) `
C. `y_2 =A sin 2pi (t//T) +x //lambda ) `
D. ` y_2=A cos 2pi (t//T- x//lambda ) `
