While doing some spring cleaning you find an old laser pointer. You take the laser into your physics laboratory to perform a double-slit experiment. The distance from the barrier to the screen is 2.50 m and the two slits are 0.350 mm apart from each other. You measure the distance from the central maximum to the 2nd order maximum and find that it is 9.04 mm. What is the wavelength of your laser pointer’s light?

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.
