Answer 1

Answer:

For hydrogen atom we know that En =

13.6

n2

Now for the transition from E,

-0.85 to E

-3.4,

-0.85-13.6/nf or nf = 16

or n = 4 and -3.4 = -13.6/n3

or n2 =2

1

Using= R(1/n2 -1/n)

we get= (1.097x 10'm1)(1/22 .

1/4)

or = 4.86 x 10"m

As the electron make the transition

from n =4 to n = 2 so it will be Balmer

series.
