In this expression, n = 5, 6, 7, c(a) Do you expect the constant
C to be greater than, less than, or equal to the Rydberg constant R?
Explain. (b) Find the numerical value of C. (c) Pickering lines with
n = 6, 8, 10, ccorrespond to Balmer lines in hydrogen with
n = 3, 4, 5, c. Verify this assertion for the n = 6 Pickering line
