The neon spectrum is very rich in the visible region. Among the many lines present, we can highlight two very close ones, with wavelengths 519.313 nm and 519.322 nm. If a light from a neon lamp falls perpendicularly over a diffraction network with 8400 lines per centimeter and if the spectrum is observed in the second order, what should be the illumination width of the network to resolve the two lines?

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.
