Calculate the ratio of the time periods (T_(1)//T_(2)) in second orbit of hydrogen atom to third orbit of He^(+) ion

Calculate the ratio of the time periods (T_(1)//T_(2)) in second orbit

1.	Calculate the ratio of the time periods (T_(1)//T_(2)) in second orbit of hydrogen atom to third orbit of He^(+) ion
Answer» Solution :TIME PERIOD `(T_(n)) = alpha (n^(2))/(Z^(2))` `:. (T_(1))/(T_(2)) = (n_(1)^(3))/(Z_(1)^(2)) xx (Z_(2)^(2))/(n_(2)^(3)) = (2^(3))/(1^(2)) xx (2^(2))/(3^(3)) = (32)/(27)`
