Which of the following expressions represents the spectrum of Balmer s

1.	Which of the following expressions represents the spectrum of Balmer series (If n is the principal quantum number of higher energy level) in Hydrogen atom?
Answer» `BAR(UPSILON) = (R(n-1) (n+1))/(n^2)` `bar(upsilon) = (R(n-2) (n+2))/(4n^2)` `bar(upsilon) = (R(n-1) (n+2))/(n^2)` `bar(upsilon) = (R(n-1) (n+1))/(4n^2)` SOLUTION :`bar(upsilon)= R (1/(2^2) - 1/(n^2)) , bar(upsilon) = (R(n-2) (n+2))/(4n^2)`
