Vedclass · Answer

(A) The violet color corresponds to a specific frequency of light emitted when electrons in $Cs$ atoms are excited by flame heat and return to the ground state. According to the relation $E = \frac{hc}{\lambda}$,energy is inversely proportional to wavelength. Violet light has a relatively short wavelength and high energy compared to other colors in the visible spectrum.

The $Cs^+$ ion imparts a violet color to the flame. How is this related to the emitted radiation?
