Question

i know that rydberg constant is 109677 cm^-1 but while using in the formuia to find ΔE =$-R_{H} = (1/n^{2})$ we use -2.18 x 10^-18 why?

Answer 1

Answer:

we have to use -2.18x 10^-18

Explanation:

because the actual value of the rydberg constant is difficult to comprehend and our present value of the rydberg constant is an approximation. also, to make calculations easier we furher convert its value to -2.18 x 10^-18
