Calculate (a) Wavenumber and (b) frequency of yellow radiation having wavelength `5800 A^(@)`.

Explanation

a) Calculation of wavelength `(bar(v))`
`lambda= 5800 A^(0) = 5800 xx 10^(-8) cm`
`=5800 xx 10^(-10) m`
`bar(v) = (1)/(lambda) = (1)/(5800 xx 10^(-10) m)`
`=1.724 xx 10^(6) m^(-1)`
`=1.724 xx 10^(4) cm^(-1)`
b) Calculation of the frequency (V)
`v= (c)/(lambda) = (3 xx 10^(8) ms^(-1) )/(5800 xxx 10^(-10) m) = 5.172 xx 10^(14) s^(-1)`
