In a young 's double slit experiment,
what chagne in the interfrence pattern do you observe,if the two slts `S_1` and `S_2` are taken as a point source?

In a Young's double slit experiment,interfernce fringes were produced on a screen placed at 1.5 m from the two slits 0.3 mm apar and illuminated by ligth of 6,400 overset@A .Find the fringe width.

In Young's double slit experiment,the slits are 0.2 mm apart.The interfernce fringes for ligth of wavelength 6,000 overset @A are formed on a screen distanct 1.5 m from the sits.Calculate the fringe width.

In a Young's double slit experiment the slit are 0.2 mm apart and the screen is 1.5 m away.It is observed that the distance between the central brigth fringe and fourth dark fringe is 1.8 cm .Find the wavelength of light used.

In a Young's double slit experiment,the separation betwen the two slits is d and the wavelength of the light is lambda .The intensity of light falling on the slit 1 is four times the intesntiy of light falling on slit 2.Choose the correct choice(s).

If amplitudes of two lights from coherent sources in Young.s double slit experiment are in the ratio 2:5, then finf the ratio of intensity at the maxima to the intensity at minima in interference pattern.

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?
