WebApr 5, 2024 · An emission spectrum is the range or array of wavelengths (spectra) obtained when the light emitted by a substance is passed through a prism and examined directly with a spectroscope. Now let's define the line emission spectrum: a spectroscope splits the emitted light into different wavelengths and gives a discontinuous spectrum in … WebDec 3, 2024 · A different discontinuous spectrum between 500 nm and 600 nm might contain every wavelength of light except 533 nm. In this case, almost every wavelength of light is included, but since 533 nm is missing, the spectrum is still discontinuous. Figure 5.14 shows several examples of discontinuous spectra in the range of visible light.
