Calculate the wave number of radiations having a frequency of 4 xx 10^

1.	Calculate the wave number of radiations having a frequency of 4 xx 10^(14) Hz
Answer» Solution :`v = 4 xx 10^(14) HZ` (i.e. `s^(-1)`) WAVE number `bar(v) = (1)/(lamda) = (v)/(c) = (4 xx 10^(14) s^(-1))/(3 xx 10^(8) MS^(-1)) = 1.33 xx 10^(6) m^(-1)" or " = (4 xx 10^(14) s^(-1))/(3 xx 10^(10) cm s^(-1)) = 1.33 xx 10^(4) cm^(-1)`
