MCQ
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$`"y"_2= "a" sin 2pi("t"/"T"-"x"/lamda)`$
- B$`"y"_2= -"a" sin 2pi("t"/"T"+"x"/lamda)`$
- ✓$`"y"_2= "a" sin 2pi("t"/"T"+"x"/lamda)`$
- D$`"y"_2= "a" sin 2pi("t"/"T"- lamda/"x")`$
