In Lloyd's experiment , the slit and its image have a separation of 4.32 mm and the obsevations made at a plane 2.0 m away fringes of separation 0.26 mm. Find the wavelength of light used.

In Lloyd's interference experiment, the path difference between direct and reflected beams of light for the 10th bright fringe was observed to be 0.63 mm. Find the wavelength of light used.

In YDSE, slits are separated by 0.24 mm and the screen is kept 160 cm away from slits. If fringe width is measured to be 0.4 cm , calculate the wavelength of light used.

In Young's double slit experiment the slits are separated by 0.24 mm. The screen is 2 m away from the slits . The fringe width is 0.3 cm. Calculate the wavelength of the light used in the experiment.

In Young's experiment, the distance between two slit is 0.8 mm and distance of screen from slit is 1.2 m. If the fringe width is 0.79 mm, then the wave length of light will be

Two slits in Young's double slits experiment are spaced 0.1 millimeter apart. If the fringe width is obtained as 5 mm on screen 1.5m away from slits. Find the wavelength of the light used.

In Young's double slit experiment, the distance between the slits is 1 mm and that between slit and screen is 1 meter and 10th fringe is 5 mm away from the central bright fringe, then wavelength of light used will be

In Young's double slit experiment, slit separation is 0.6 mm and the separation between slit and screen is 1.2m . The angular width is (the wavelength of light used is 4800Å )

In Young's double slit experiment the slits are 0.5 mm apart and interference is observed on a screen placed at a distance of 100 cm from the slits. It is found that the 9^(th) bright fringe is at a distance of 8.835 mm from the second dark fringe from the centre of the fringe pattern. Find the wavelength of light used.
