Question # If ( 9.9 mathrm{eV} ) energy is supplied to ( mathrm{H} ) atom, the no of spectral lines emitted is equal to :

# If ( 9.9 mathrm{eV} ) energy is supplied to ( mathrm{H} ) atom, the no of spectral lines emitted is equal to :

(1) 0

(2) 1

(3) 2

(4) 3

Solution

It ( 9 cdot 9 ) eV is supplicd

[

begin{array}{l}

end{array}

]

( 9.9 e v<(13.6-3.4) )

these No trangation

thus No Spectral lines

[

Ans=0
