An instructor wishes to determine the wavelength of the light in a laser beam. To do so, she directs the beam toward a partition with two tiny slits separated by 0.195 mm. An interference pattern appears on a screen that lies 4.85 m from the slit pair. The instructor's measurements show that two adjacent bright interference fringes lie 1.57 cm apart on the screen. What is the laser's wavelength (in nm) ?

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.
