This figure shows a double slit located a distance x from a screen, with the distance from the center of the screen given by y. When the distance d between the slits is relatively large, there will be numerous bright spots, called fringes. It can be shown that, for small angles (where sin ? ?, with ? in radians), the distance between fringes is given by Δy = x?/d. Using this result, find the wavelength of light that produces fringes 7.50 mm apart on a screen 2.00 m from double slits separated by 0.110 mm. =___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.
