PHXII10:WAVE OPTICS

368020 For Young's double slit experiment, two statements are given below
Statement A :
If screen is moved away from the plane of slits, angular separation of the fringes remains constant.
Statement B :
If the monochromatic source is replaced by another monochromatic source of larger wavelength, the angular separation of fringes decreases.

In the light of the above statements, choose the correct answer from the options given below:

1 Both Statement A and Statement B are false.
2 Statement A is true but Statement B is false.
3 Statement A is false but Statement B is true.
4 Both Statement A and Statement B are true.

368021 In a double slit experiment, the coherent sources are spaced \(2{\rm{ }}d\) apart and the screen is placed a distance \(D\) from the slits. If \({n^{th}}\) bright fringe is formed on the screen exactly opposite to a slit, the value of \(n\) must be

1 \(\frac{{2{d^2}}}{{\lambda D}}\)
2 \(\frac{{{d^2}}}{{\lambda D}}\)
3 \(\frac{{{d^2}}}{{4\lambda D}}\)
4 \(\frac{{{d^2}}}{{2\lambda D}}\)
PHXII10:WAVE OPTICS

368022 In a YDS setup, the distance between the plane of the slits and the screen is increased by \({20 \%}\) and the distance between the slits is increased by \({50 \%}\). Then the percentage change in fringe width is

1 \({80 \%}\)
2 \({20 \%}\)
3 \({66 \%}\)
4 \({44 \%}\)
PHXII10:WAVE OPTICS

368023 In a Young's double slit experiment, the separation between the two slits is \(0.9\;mm\) and the fringe are observed \(1\;m\) away. If it produces the second dark fringe at a distance of \(1\;mm\) from the central fringe, the wavelength of the monochromatic source of light used is

1 \(450\;nm\)
2 \(400\;nm\)
3 \(500\;nm\)
4 \(600\;nm\)
