MCQ
The spectrum of iodine gas under white light will be
  • A
    Only violet
  • B
    Bright lines
  • C
    Only red lines
  • Some black bands in continuous spectrum

Answer

Correct option: D.
Some black bands in continuous spectrum
d
When white light strikes an object, some light is absorbed, and some is reflected. The colours that we see are those that are reflected, and the colours that we don't see are absorbed by the material.Iodine absorbs mostly green light so Violet-Purple Colour band is observed with some Black Bands in Continuous Spectrum.
