A) Source \[{{S}_{1}}\] emits wave (1) and \[{{S}_{2}}\] emits wave (2)
B) Source \[{{S}_{3}}\] emits wave (3) and \[{{S}_{4}}\] emits wave (4)
C) Source \[{{S}_{2}}\] emits wave (2) and \[{{S}_{4}}\] emits wave (4)
D) \[{{S}_{4}}\] emits waves (4) and \[{{S}_{3}}\] emits waves (3)
Correct Answer: C
Solution :
For interference, two waves must have a constant phase relation ship. Equation ?1? and ?3? and ?2? and ?4? have a constant phase relationship of \[\frac{\pi }{2}\] out of two choices. Only one S2 emitting ?2? and S4 emitting ?4? is given so only option is correct.You need to login to perform this action.
