Young's double slit experiment is set up in your physics lab. The instructor directs laser light through two slits that are 0.300 mm apart and an interference pattern is displayed on a far wall that is 6.80 from the slits. The interference pattern consists of alternating dark and bright bands of light. With a meterstick you carefully and accurately measure the average distance between the dark bands as 1.02 cm. What is the frequency (in 1014 Hz units) of the laser 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.
