Calculate the wavelength, frequency, and wave number of a light wave whose period is `2.0 xx10^(-10) s`.

Explanation

Frequency (v) `=(1)/("Period")=(1)/((2.0 xx 10^(-10)s))=5.0 xx 10^(9) s^(-1)`
Wavelength `(lambda)=(c)/(v)=((3xx10^(8) ms^(-1)))/((5xx10^(9) s^(-1)))=6.0 xx 10^(-2)m`
Wave number `(bar(v))=(1)/(lambda)=(1)/((6.0 xx 10^(-2)m)) =16.66 m^(-1)`.
