In a Young's double slit experiment set-up source S of wavelength 5000A^(@) illuminates two slits S_(1) and S_(2). Which act as two coherent sources. The source S oscillates about its shown position according to the equation y = 0.5 sin pi t. where y is in millimeters and t in second. Find positions of central maxima as a function of time with respect to 'O'

Answer»

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