23. which of the following is a continuous spectrum crossed by dark lines? absorption spectrum emissions spectrum continuous spectrum visible spectrum
Answer
Brief Explanations:
An absorption spectrum is formed when light passes through a substance and certain wavelengths are absorbed, resulting in a continuous spectrum crossed by dark lines corresponding to the absorbed wavelengths. Emission spectra have bright lines against a dark background. A continuous spectrum has no dark or bright lines within it in the way described. The visible spectrum is a part of the electromagnetic spectrum and does not inherently have dark - lines crossing a continuous spectrum in this context.
Answer:
absorption spectrum
