The frequency of a wave of light is 12xx10^14 s^(-1) . The wave number

1.	The frequency of a wave of light is 12xx10^14 s^(-1) . The wave number associated with this light is
Answer» `5XX10^(-7) m` `4XX10^(-8) cm^(-1)` `2xx10^(-7) m^(-1)` `4xx10^(4) cm^(-1)` Solution :Frequency `v=12xx10^14 s^(-1)` and VELOCITY of light `c=3xx10^10 cm s^(-1)` . We know that the wave number `barv=v/c =(12xx10^14)/(3xx10^10)=4xx10^4 cm^(-1)`
