Question

value of rydberg constant is ​

Answer 1

Answer:

The value of rydberg constant is 109737 $cm^{-1}$

Explanation:

Rydberg constant is a physical constant relating to the electromagnetic spectra of an atom.

Rydberg constant R = (2π × πm$e^{4}$) ÷ (c$h^{3}$)

where,

π = 3.14

m = mass of electron = $9.108 * 10^{-28}$ g

e = charge of electron = $4.8 *10^{-10}$ esu

c = speed of light = $2.9979*10^{10}$ cm/s

h = planks constant = $6.626*10^{-27}$ erg.s

Substituting the values in the above equation,

R = $\frac{2*(3.14)^{2}*9.108 * 10^{-28} *(4.8 *10^{-10})^{4} }{2.9979*10^{10}*(6.626*10^{-27})^{3} }$

   = 109737 $cm^{-1}$
