1.	Calculate the wavelength, frequency and wave number of a light wave whose period is 2.0 xx 10^(-10)s
Answer» Solution :Frequency `(v) =(1)/("Period") = (1)/(2.0xx 10^(-10)s) = 5 xx 10^(9) s^(-1)` WAVELENGTH, `lamda = (c)/(v) = (3.0 xx 10^(8) MS^(-1))/(5 xx 10^(9) s^(-1)) = 6.0 xx 10^(-2) m` WAVE number, `bar(v) = (1)/(lamda) = (1)/(6 xx 10^(-2)m) = 16.66 m^(-1)`
