Homework Answers

Answer #1

Continuum sources and Line sources are the sources of electromagnetic radiation.

Continuum sources:

  • They emit radition over a broad range of wavelengths.
  • Its intensity of emission differs slowly as a function of wavelength.

Examples of Continuum sources are:

  1. Tungsten filament lamp (visible radiation)
  2. Heated solid ceramics (IR region)
  3. Deuterium lamp (UV radiation)
  4. Xenon arc lamp (UV-VIS region).

Line sources:

  • They emit only a few discrete wavelengths of light.
  • Its intensity is a function of wavelength.

Examples of Line Sources:

  1. Hollow cathode lamp (UV-VIS region)
  2. Sodium vapour lamp (UV-VIS region)
  3. Electrodeless discharge lamp (UV-VIS region)
  4. Lasers (UV-VIS and IR regions)
