Calculate (a) wavenumber and (b ) frequecy of yellow radiation having wavelength 5800 A

Text Solution

Verified by Experts

(a ) Calculation of frequency (v ):
`v= (c )/(lambda) `
`=(3.0 xx 10^(8) ms^(-1))/( 580 xx 10^(-9) m) `
5.1724 `xx 10^(14) s^(-1)`
where c= wave length
`=3.0 xx 10^(8) ms^(-1)`
`lambda` = wavelength = 580 nm
=580 `xx 10^(9) m`
`=580 xx 10^(9) m`
( b) Calculation of wave number ( v) :
`vec( v) + (1)/(lambda) = (1)/( 580 xx 10^(9) m) `
`=1.7241 xx 10^(6) m^(-1)`
`1.7241 xx 10^(4) cm^(-1)`
