Answer 1

/1Answer:

It is balmer

Explanation:-

There is no such explanation to that, just use-

1/Λ= Rz²(1/n1²-1/n2²)

where n1 is smaller than n2. If the answer lies between 4000A to 6000A, then the light emmited is in visible spectrum. You can take 1/R as 910 and Z is atomic No. Of the atom used.
