Calculate the wavelength frequency and wave number of a light wave whose period is 2.0 `xx 10^(10) s`

Text Solution

Verified by Experts

Frequency (v ) = `(1)/( "Periodic ") = (1)/( 2.0 xx 10^(10)s)`
wavelength `(lambda) = (c )/(v ) = (3.0 xx 10^(8) ms^(-1))/( 5.0 xx 10^(9) s^(-1))`
Wave number `(v ) = (1)/(lambda) = (1)/( 6.0 xx 10^(2) m) `
`=16 .67 m^(-1)`
