Question

what evidence can you cite that the interstellar medium contains both gas and dust? (select all that apply.)

Answer 1

(a) The gas of interstellar medium can be detected from the radiations of photons of  wavelength 21 cm.

(b) The gas of interstellar medium can be detected from the absorption lines present in the light from distant stars, which must be caused by a medium of density and temperature other than that of the stars emitting the lights.
