Question

Calculate the wave number of the highest
energy transition in the Balmer series of
Hydrogen atom [R = 109678 cm )
(T.S Agri-2017)
1) 27419.5 cm-1 2) 2741.95 cm-1
3) 274.195 cm-1 c4) 274195.1cm-1 pls help​

Answer 1

Answer:

correct option is 4th

Explanation:

first the highest energy transition is from infinity to the n =2nd shell of hydrogen atom then use the formulla of limiting spectrum lines and find the wave length

and as we know wave no is inverse of wave length... so u can easily find wave no.

Thank you!
