If screen is shifted in x direction away from source then which of the following is incorrect?
1 Angular width of fringe does not change due to shifting
2 Position of all maxima are changing
3 Fringe width remains constant
4 Central maxima is shifted along x-axis

If n is the number of positive integral solution of x_(1), x_(2)x_(3)x_(4) = 210 , then which of the following is incorrect ?

Find the slopes of the lines which make the following angles with the positive direction of x-axis: pi/4 ii. (2pi)/3

In YDSE when slab of thickness t and refractive index mu is placed in front of one slit then central maxima shifts by one fringe width. Find out t in terms of lambda and mu .

In Young's double-slit experiment, let A and B be the two slit. A thin film of thickness t and refractive index mu is placed in front of A. Let beta = fringe width. Then the central maxima will shift

A light wave is incident normally over a slit of width 24xx10^-5cm . The angular position of second dark fringe from the central maxima is 30^@ . What is the wavelength of light?

If the origin is shifted (1, 2, -3) without changing the directions of the axis, then find the new coordinates of the point (0, 4, 5) with respect to new frame.

In a single slit differaction pattern a monochromatic light of wavelength 500nm is used if angular position of the point where waves interfere from slit is 10^(-3) radians from line of central maxima. If width of the slit is 500 mum , then order of minima obtained on screen will be

In a Lloyds's mirror experiment as narrow slit S transmitting a light of wavelength lambda is placed 3 mm above a small plane mirror ( as shown). The light coming directly from the the slit and that coming after the reflection interfere on a screen placed at a distance of 90 cm from the slit. Length of mirror is 2 mm and the middle point of mirror is 2 mm from point P. If the mirror is shifted towards left then how does the fringe pattern on screen changes ?

In the circuit arrangement shown in figure capacitor is initially unchanged At t = 0 switch is thrown to position '1' it remains closed till the current in the circuit becomes 50 % of maximum current then. Suddenly switch is shifted to position '2' (Assume all batteries are ideal) Which of the following is the correct options after switch is shifted to position '2'.

In a YDSE experiment, the distance between the slits & the screen is 100 cm . For a certain distance between the slits, an interference pattern is observed on the screen with the fringe width 0.25 mm . When the distance between the slits is increased by Deltad=1.2 mm, the fringe width decreased to n=2//3 of the original value. In the final position, a thin glass plate of refractive index 1.5 is kept in front of one of the slits & the shift of central maximum is observed to be 20 fringe width. Find the thickness of the plate & wavelength of the incident light.
