Question

After reflection from the open end, a transverse progressive wave y_I = a sin `2pi("t"/"T" - "x"/lambda)` travels along the direction of negative X-axis. The equation of the reflected wave will be ______.

विकल्प

• `"y"_2= "a" sin 2pi("t"/"T"- lamda/"x")`

• `"y"_2= -"a" sin 2pi("t"/"T"+"x"/lamda)`

• `"y"_2= "a" sin 2pi("t"/"T"+"x"/lamda)`

• `"y"_2= "a" sin 2pi("t"/"T"-"x"/lamda)`

Answer 1

After reflection from the open end, a transverse progressive wave y_I = a sin `2pi("t"/"T" - "x"/lambda)` travels along the direction of negative X-axis. The equation of the reflected wave will be `"y"_2 = a sin 2pi ("t"/"T"+"x"/lamda)`.
