Two narrow slits are illuminated by a laser with a wavelength of 502 nm. The interference pattern on a screen located x = 4.80 m away shows that the second-order located y = 8.90 cm away from the central bright fringe. Calculate the distance between the two slits. 5.42x10-3 cm Computer's answer now shown above. You are correct. Previous Tries Your receipt no. is 158-5046 + The screen is now moved 1.5 m further away. What is the new distance between the central and the second-order bright fringe? 6.11E-2 m Either you perform similar calculations as for the previous problem, or you can use the fact that the ratio of fringe separation to screen-distance stays constant.

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.
