In a Young.sdouble slit experiment set - up sourceS of wavelength5000 A^(0)illuminates twoslits s_(1) and S_(2)Which act as two coherentsources . The source S oscillates about is shownposition accodingto the equation y =0.5 sin pit . wherey is millimeteres and t in second.Find secondof centralmaxima as a function oftime with respectto .O.

Answer»

`y = ( cos 2 PI t) MM`
`y = - (SIN pi t) mm `
`y = -(cos 2pit) mm`
`y = (sin 2pit) mm`
