368043 Statement A :
In Young’s double slit experiment interference pattern disappear when one of the slits is closed.
Statement B :
Interference occurs due to superimposition of light waves from two coherent sources.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.

368044 In young’s double slit experiment fifth dark fringe is formed opposite to one of the slit. If \(D\) is the distance between the slits and the screen and \(d\) is the separation between the slits, then the wavelength of light used is

1 \(\frac{{{d^2}}}{{5D}}\)
2 \(\frac{{{d^2}}}{{9D}}\)
3 \(\frac{{{d^2}}}{{6D}}\)
4 \(\frac{{{d^2}}}{{15D}}\)

368045 The width of fringe is \(2\,mm\) on the screen in a double slits experiment for the light of wavelength of \(400\,nm\). The width of the fringe for the light of wavelength \(600\,nm\) will be

1 \(4\,mm\)
2 \(2\,mm\)
3 \(3\,mm\)
4 \(1.33\,mm\)

PHXII10:WAVE OPTICS

368046 In Young's double slit experiment, the distance between slits and the screen is \(1.0\,m\) and monochromatic light of \(600\,nm\) is being used. A person standing near the slits is looking at the fringe pattern. When the separation between the slits is varied, the interference pattern disappears for a particular distance \(d_{0}\) between the slits. If the angular resolution of the eye is \(\dfrac{1^{\circ}}{60}\) the value of \({d_o}\) is close to

1 \(2\;\,mm\)
2 \(1\,mm\)
3 \(3\,\;mm\)
4 \(4\,mm\)
