When an electron is an excited hydrogen atom, jumps from n = 4 to n= 2 level, green light is emitted . Which colour of light will be observed, if the electron jumps from n=6 to n=2 ?

Options

A. Red
B. Violet
C. Yellow
D. Orange

Answer

B

Explanation

`E=hv = (hc)/(lamda)`
As the difference in energy increases, the emitted energy also increases.
`because E prop 1/lamda " or " lamda prop 1/E, lamda` will decrease. Violet colour is observed . `lamda_R, lamda_V, " and " lamda_O` are more than `lamda_("green")`
