If wavelength of a wave is ` lambda = 6000 Å `.Then wave number will be

A

`1.66 xx 10^(7) ` per m

B

`1.66 xx 10^(6)` per m

C

`166xx10^(3)` per m

D

` 16.6 xx 10^(-1)` per m

Text Solution

Verified by Experts

The correct Answer is:
B
Wave number `=(1)/(lambda)=(1)/(6 xx 10^(-7))=1.66 xx 10^(6)//m` .
