In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion:In Young's double slit experiment,the two slits are at distnace d apart.Interference pattern is obsreved on the screen .When it is directly opposite to one of the slits a dark fringe is observed.Then,the wavelength of the wave is proportional to the square of th distnce fo the slits. Reason:For a dark fringe,the i ntensity is zero.

If white light is used in the Newton's ring s experiment ,the color observed in the reflected light is complementary to that observed in the transmitted light through the same point. This is due to

A point source S emitting light of wavelength 600 nm is placed at a very small height h above a flat reflecting surface AB [Fig.6.07].The intensity of the reflected light is 36% of the incident intensity.Interfrerence fringes are observed on a screen placed parallel to the reflecting surface at a very large distance D from it. What is the shape of the interference fringes on the screen?

What change is observed in interference pattern of Young's double slit experiment ,if one of the two slits is painted,so that it transmits half the light intensity of the other?

What is the apparent change in frequency when source and observer move with same velocity in the same direction?

In a Young's double slit experiment,12 fringes are observed to be formed in a certain segment of the screen,when light of wavelength 600 nm is used.If the wavelength of light is changed to 400 nm ,number of fringes observed in the same segment of the screen is given by

General instruction same as in chapter 1. Assertion: No interference pattern is detected when two coherent sources are infinitely close to each other. Reason:The Fringe width is inversly proportional to the distance between the two slits and a singel fringe may occupy the whole screen.

In Young's double slit experiment,usin light of wavelength 400 nm,interference fringes of width X are obtained .The wavelength of light is increassed to 600 nm and the separation between the slits is halved.If one wants the observed fringe width on the screen to be the same in the two caes,find the rati of the distance between the screen and the plane of the interfering sources in the two arrangements.

The Young's double-slit experiment is done in a medium of refractive index 4//3. A light of 600 nm wavelength is falling on the slits having 0.45 mm separation. The lower shift S_(2) is covered by a thin glass sheet of thickness 10.4 mm and refractive index. 1.5. The interference pattern is observed on a screen placed 1.5 m from the slits as shown in Figure Find the light intensity of point O relative to the maximum fringe intensity.
