Young’s Double Slit Experiment
PHXII10:WAVE OPTICS

368006 If Young's double slit experiment is performed in water instead of air, then

1 no fringes would be seen
2 fringe width would decrease
3 fringe width would increase
4 fringe width would remain unchanged

368007 In a double-slit experiment the angular width of a fringe is found to be \(0.2^\circ \) on a screen placed \({\rm{ }}1{\rm{ }}m\) away. The wavelength of light used is \(600\,nm\).What will be the angular width of the fringe if the entire experimental apparatus is immersed in water? Take refractive index of water to be \(4/3\).

1 \(0.30^\circ \)
2 \(0.15^\circ \)
3 \(0.45^\circ \)
4 \(0.27^\circ \)
