What is the advantage of a diffraction grating over a double slit in dispersing light into a spectrum?
The light splits more easily because the slit widths are so narrow.
When light passes through a prism or droplets of water, it produces a spectrum, which is a range or band of colors.
We get a bigger number of matches on the cover if we use a diffraction grating with multiple slits, i.e., a larger number of interference minima or maxima. Since there is constructive interference in the maxima, they are regarded as lighter components.
Also, since the slit widths are so narrow, the light splits more easily, allowing us to view the full range of colors.
An electric current through hydrogen gas produces several distinct wavelengths of visible light. What are the wavelengths of the hydrogen spectrum, if they form first-order maxima at angles of, and role="math" localid="1654239338245" when projected on a diffraction grating having lines per centimeter?
