Question

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

Answer 1

Answer:

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.
