Figure shows a Young's double slit experiment set-up. The source S of wavelength 4000Å oscillates along y-axis according to the equation y-sinpit, where y is in millimeters and t is in seconds. The distance two slits S_(1) and S_(2) is 0.5 mm.

Answer»

The position of CENTRAL maxima as a function of time is `4 SIN pi t`
The position of central maxima as a function of time is `-4 sin pi t`
The instant at which maximum intensity occurs at P for the first time is `(1)/(pi) sin^(-1)""((59)/(80))`
The instant at which minimum intensity occurs at P for the first time is `(1)/(pi) sin^(-1)""((27)/(80))`
