What type of spectrum, if any, would be produced if the light radiated by a heated atomic gas were to be dispersed through a prism? A. a continuous band of color B. a continuous band of color with some dark lines (missing wavelengths) C. only blue light D. only red light E. discrete lines of different colors

E. discrete lines of different colors

Explanation:

When light passes through a heated atomic gas and then dispersed through the prism, A line spectrum is obtained always. This happens because when, heated atoms of the gas will be in excited state, these excited state atoms t will emit lights of specific frequency particular to the gas. Thus, a spectra containing lines of discrete colors is obtained on the screen.

Hence, option E is correct.
