Calculate the value of Rydberg's constant given `m=9.1xx10^(-31) kg, e = 1.6 xx10^(-19)c, epsilon _(0) = 8.854xx10^(-12) Fm^(-1) , c = 3 xx10^(8)ms^(-1),h=6.625xx10^(-34)Js.`

Text Solution

Verified by Experts

Rydberg's constant,
`R=(me^(4))/(8epsilon_(0)^(2)ch^(3))`
`=(9.1xx10^(-31)xx(1.6xx10^(-19))^(4))/(8xx(8.854xx10^(-12))^(2)xx3xx10^(8)xx(6.625xx10^(-34)))=1.089xx10^(7)m^(-1)`
