A laboratory experiment uses light with a wavelength of 556 nm and a double-slit with spacing 5 μm to produce a double-slit interference pattern on a screen, as shown below. Light waves meet at P after traveling distances r₁ and 12. Answer: Double slit 0 Enlarged below L "₁ 12 P Viewing screen How many bright fringes will be visible on the screen? Round down to the nearest integer, giving your answer with 0 (zero) decimal places. Hint: keep in mind that in addition to the central maximum, there are an equal number of maxima above and below the horizontal dashed line.

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.
