Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Question

An instructor wishes to determine the wavelength of the light in a laser beam. To do so, he directs the beam toward a partition with two tiny slits separated by 0.195 mm. An interference pattern appears
on a screen that lies 4.95 m from the slit pair.
The instructor's measurements show that two adjacent bright interference fringes lie 1.60 cm apart on the screen.
What is the laser's wavelength (in nm) ?
63

Find the formula that gives the locations of bright fringes in a two-slit interference pattern as functions of wavelength, slit separation, and screen distance. Note that the distance between adjacent bright
fringes is the same as the position of the m = +1 fringe, because adjacent fringes are separated by adjacent integer values for m. Be careful with units. nm
