Young’s Double Slit Experiment
PHXII10:WAVE OPTICS

368141 In the Young's double slit experiment using sodium light (\(\lambda = 5898\) \( \mathop A^{~~\circ} \)), 92 fringes are seen. If the green colour light (\(\lambda = 5461\) \( \mathop A^{~~\circ} \)) is used, how many fringes will be seen

368142 Young’s double slit experiment is carried out by using green, red and blue light, one colour at a time. The fringe width recorded are \({\beta _{G,}}\,{\beta _R}\) and \({\beta _{B,}}\) respectively. Then

1 \({\beta _G} > {\beta _B} > {\beta _R}\)
2 \({\beta _B} > {\beta _G} > {\beta _R}\)
3 \({\beta _R} > {\beta _B} > {\beta _G}\)
4 \({\beta _R} > {\beta _G} > {\beta _B}\)

368143 Assertion :
In Young’s experiment the fringe width for dark fringe is same from that for white fringes.
Reason :
In Young’s double slit experiment, when a source of white light is used, then only black and bright fringes are observed.

1 Both Assertion and Reasons are true and the Reason is a correct explanation of the Assertion.
2 Both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
3 Assertion is true but the Reason is false.
4 Assertion is false but Reason is true.

II. A slit \(S\) is not needed if we use an ordinary but well collimated beam of light.
III. A slit \(S\) is not needed if we use a spatially coherent source of light.
