2. In class you will have seen the equations given above. Note the values recorded: L is the distance from the double-slit grating to the screen (2.5 meters in this case) and d is the distance between slits (.125 mm.) 3. In the next figure you can see the spread of light. Note the central maximum and pairs of bright fringes. I measured the distance between the 2nd bright fringes (m=2) to be 4.2 cm. 4. Using the values recorded above, and the relevant expression(s) from chapter 17, show the work done to find the wavelength of the diode laser, and record the wavelength value below. How does that value compare to the listed range of 660 nm – 680 nm (for red lasers) or 532 nm (for green ones)?

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.
