In Young’s experiment, if a slab of mica of refractive index m and thickness of t is introduced in the path of light from one of the slits, then number of fringes formed on the screen will –CorrectIncorrect
In a Young’s double-slit experiment, the intensity of the central maximum is I0. The width of one slit is now doubled. The intensity at the point where the intensity was originally 0.5 I0 will now be –CorrectIncorrect
Four independent waves are expressed as
y1 = a1 sin wt, y2 = a2 sin wt, y3=a3 cos wt and y4 = a4 sin (wt + π/3). The interference is possible betweenCorrectIncorrect
If two coherent light waves produce minima of fifth order, the path difference between the waves is –CorrectIncorrect
In double slit experiment, when interference pattern is observed by white light by observer, through a transparent glass of green colour, he finds black and green bright fringes. What happens if green glass is replaced by violet colour glass –CorrectIncorrect
In young’s double slit experiment, a glass plate is placed before a slit which absorbs half the intensity of light. Under this case –CorrectIncorrect
The intensity of two waves is 2 and 3 unit, then average intensity of the light in the overlapping region will have the value –CorrectIncorrect
In young’s experiment with yellow light
(λ = 5800Å) 70 fringes are observed. If violet light (λ = 4358Å) is used then fringes will beCorrectIncorrect
In double slit experiment using light of wavelength 600 nm, the angular width of a fringe formed on a distant screen is 0.1°. What is the spacing between the two slits ?CorrectIncorrect
Which of the following is true:-CorrectIncorrect
