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

Explanation

( a) calculate of wavenumber `bar(v)`
`lambda= 5800A = 5800xx10^(-8)cm`
= `5800 xx10^(-10)m`
`barV1/lambda=1/(5800xx10^(-10)m)`
`1.724xx10^(6)m^(-1)`
`1.724xx10^(4) cm ^(-1)`
(b) calculation of the ferquency (v)
`barv=c/lambda=(3xx10^(8)ms^(-1))/(5800xx10^(-10)m)=5.172xx10^(14)s^(-1)`
