The figure shows a double slit experiment with P and Q as the slits. The path lengths PX and QX are nlambda and (n+2)lambda respectively, where n is a whole number and lambda is the wavelength. Taking the central fringe as zero, what is formed at X?

In Young's double slit experiment, the distance between two coherent sources is 1 mm and the distance between the slits and the screen is 1 m. If the 10th dark fringe is at a distance of 4.75 mm from the central bright fringe, calculate the wavelength of light used and

In a double slit experiment, the separation between the slits is d and distance of the screen from slits is D. If the wavelength of light used is lambda and I is theintensity of central bright fringe, then intensity at distance from central maximum is

In Young's double slit experiment, the distance between two coherent sources is 1 mm and the distance between the slits and the screen is 1 m. If the 10th dark fringe is at a distance of 4.75 mm from the central bright fringe, calculate the distance of 5th bright fringe from the central bright fringe.

In Young's double slit experiment, the two slits acts as coherent sources of equal amplitude A and wavelength lambda . In another experiment with the same set up the two slits are of equal amplitude A and wavelength lambda but are incoherent. The ratio of the intensity of light at the mid-point of the screen in the first case to that in the second case is

In young's double-slit experiment, the slit are 2 mm apart and are illuminated with a mixture ot two wavelengths lambda_(0) = 750 nm and lambda = 900 nm , The minimum distance from the common central bright fringe on a screen 2 m from the slits, where a bright fringe from one interference pattern coincides with a bright fringe from the other, is

In a Young's double slit experiment, the slits are 2mm apart and are illuminated with a mixture of two wavelength lambda_0=750nm and lambda=900nm . The minimum distance from the common central bright fringe on a screen 2m from the slits where a bright fringe from one interference pattern coincides with a bright fringe from the other is

In a standard Young's double-slit experiment set-up, two point P and Q are marked on the screen Path difference corresponding to point P is lambda//2 and for point Q it is lambda//4 . Here lambda is wavelength of light being used. If I_P and I_Q are the resultant intensities at points P and Q, then I_Q//I_P is

Two coherent sources A & B emitting light of wavelength lambda are placed at position (-D,0) and (-D,3lambda) respectively Here D gt gt lambda The number of minima on y-axis and maxima on x-axis respectively are
