A double-slit experiment is performed with light of wavelength 600 nm. The bright interference fringes are spaced 1.8 mm apart on the viewing screen. What will the fringe spacing be if the light is changed to a wavelength of 400 nm?

The width of a slit is 1.9 x 10-5 m. Light with a wavelength of 520 nm passes through this slit and falls on a screen that is located 0.55 m away. In the diffraction pattern, find the width of the bright fringe that is next to the central bright fringe.

Fringes in the Thomas Young experiment are produced using sodium light of wavelength 495 nm and two slits which are 1.2 mm apart. If the fringes are formed on a screen 1.0 m away from the slits, how far is the third order bright fringe from the middle of the screen? Give your answer in millimeters (mm).

In a Young’s Double Slit Experiment the distance between two slits is 0.150 mm and the length from the double slit to the screen is 120 cm. The distance from central fringe to the nth fringe is 2 cm. The wavelength of the light is 750 nm. What is the path difference for the rays from the two slits arriving at a point on the screen, say point P?
