Vedclass · Answer

(A) The $Cs^{+}$ ion imparts a violet colour to the Bunsen flame.The energy of a photon is given by the equation $E = h
u = \frac{hc}{\lambda}$.Violet light has a shorter wavelength $(\lambda)$ compared to other visible colours like red,which implies it has a higher frequency $(
u)$ and consequently higher energy $(E)$.Therefore,the emission of violet light corresponds to the transition of electrons involving high energy.

List-$I$ (Salt)	List-$II$ (Flame colour wavelength)
$(a)$ $LiCl$	$(i)$ $455.5 \text{ nm}$
$(b)$ $NaCl$	$(ii)$ $670.8 \text{ nm}$
$(c)$ $RbCl$	$(iii)$ $780.0 \text{ nm}$
$(d)$ $CsCl$	$(iv)$ $589.2 \text{ nm}$

$Cs^{+}$ ions impart violet colour to Bunsen flame. This is due to the fact that the emitted radiations are of
