Consider the given arrangement. The two slits S₁ and S₂ are illuminated by monochromatic light of wavelength λ. Slits S₃ and S₄ are at separation d₁ = λD/(3d), then ratio of maximum and minimum intensity on the screen will be

For Young's double slit experiment, two statements are given below:

Statement I: If screen is moved away from the plane of slits, angular separation of the fringes remains constant.

Statement II: 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:

In a Young's double slit experiment, a student observes 8 fringes in a certain segment of screen when a monochromatic light of 600nm wavelength is used. If the wavelength of light is changed to 400nm, then the number of fringes he would observe in the same region of the screen is:

In Young's double slit arrangement, slits are separated by a gap of 0.5 mm, and the screen is placed at a distance of 0.5 m from them. The distance between the first and the third bright fringe formed when the slits are illuminated by a monochromatic light of 5890 Å is:

A beam of electrons of energy E scatters from a target having atomic spacing of IÅ °. The first maximum intensity occurs at θ = 60°. Then E (in eV) is (Planck constant h = electron mass m = 9.1 * 10?³¹ kg )

A Young's double-slit experiment is performed using monochromatic light of wavelength λ. The intensity of light at a point on the screen, where the path difference is λ, is K units. The intensity of the light at a point where the path difference is λ/6 is given by nK/12, where ' n ' is an integer. The value of ' n ' is

Orange light of wavelength 6000 * 10^-10 m illuminates a single slit of width 0.6 * 10^-4 m. the maximum possible number of diffraction minima produced on both sides of the central maximum is

A beam of plane polarized light of large cross-sectional area and uniform intensity of 3.3Wm⁻² falls normally on a polarizer (cross sectional area 3 * 10⁻⁴ m² ) which rotates about its axis with an angular speed of 31.4rad/s. The energy of light passing through the polariser per revolution, is close to:
