Calculate Rh using the combination between the equations 1 and 2 based on

1/ λ = (Rh) (1/n2in – 1/n2out) and calculate the average of the values and the %error

Equation 1: Ephoton = |ΔE|= Eout – Ein = B( 1/nin2 – 1/nout2)

Equation 2: λ= hc/Ephoton

Given:

colour	Wavelength obtained (nm)	N (out)	N (in)	Rh calculated m-1
red	644.1	3	2
turquoise	518.8	4	2
violet	438.0	5	2
Violet (faint)	385.1	6	2

Average Rydberg constant, m-1 = ?
