In a Young’s double slit experiment, the path difference at a certainpoint on the screen between two interfering waves is 𝟏𝟖th of thewavelength. The ratio of intensity at this point to that at the centreof a bright fringe is close to(i) 0.80(ii) 0.74(iii) 0.94(iv) 0.85

In a Young's double slit experiment the separation of the slits is 0.23 mm. The distance to the screen is 1.12 m. The third bright fringe is a distance of 5.9 mm from the central fringe. Determine the wavelength of the light.

In Young's experiment, the interference pattern is found to have an intensity ratio between the bright and dark fringes as 9. What is the ratio of intensities and amplitudes of the two interfering waves, respectively? (A) 4,2 (B) 9,3 (C) 2.25,1.5 (D) None of thes

A Young's double-slit experiment is performed using monochromatic light of wavelength λλ. The intensity of light at a point on the screen, where the path difference is λλ, is KK units. The intensity of light at a point where the path difference is λ6λ6 is given by nK12nK12, where nn is an integer. The value of nn is

Light of a single frequency is incident on a pair of narrow slits that are a distance of 0.10 mmapart. A series of bright and dark fringes is observed on a screen a distance of 2.0 m away.

In Young\'s experiment, monochromatic light is used to illuminate the two slits A and B. Interference fringes are observed on a screen placed in front of the slits. Now if a thin glass plate is placed normally in the path of the beam coming from the slit
