In a double slit pattern `(lambda = 6000Å)`, the first order and tenth order maxima fall at 12.50 mm and 14.55mm from a particular reference point. If `lambda` is changed to 5500Å, find the position of zero order and tenth order fringes, other arrangements remaining the same.

In a double-slit pattern (lambda=6000Å) , the zero-order and tenth-order maxima fall at 12.34 mm and 1473mm from a particular reference point. If lambda is changed to 5000Å , find the position of the zero order and tenth order fringes, other arrangements remaining the same.

In an interference pattern the position of zeroth order maxima is 4.8 mm from a certain point P on the screen. The fringe width is 0.2 mm. The position of second maxima from point P is

In an interference pattern produced by using a biprism, the zeroth order maxima is at a distance of 4.7mm from a point P on the screen. If the fringe width is 0.2 mm, then the distance of the second minima from the point P will be

In Young's double slit experiment, the slits are 0.5mm apart and interference pattern is observed on a screen placed at a distance of 1.0m from the plane containg the slits. If wavelength of the incident light is 6000Å , then the separation between the third bright fringe and the central maxima is

A parallel beam of light of all wavelength greater than 3000Å falls on a double slit in a Young's double slit experiment. It is observed that the wavelength 3600Å and 6000Å are absent at a distance of 31.5 mm from the position of the centre maximum and the orders of the interference at this point for the two wavelength differ by 7. If the distance between the slit and the screen in 1m, the separation between the two slits is

Light of wavelength 6000Å is incident on a slit of width 0.30 mm. The screen is placed 2 m from the slit. Find (a) the position of the first dark fringe and (b). The width of the central bright fringe.
