If wavelength of a wave is lambda = 600...

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

A

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

B

`1.66 xx 10^(6) m^(-1)`

C

`1.66 xx 10^(7) m^(-1)`

D

`1.66 xx 10^(3) m^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
Wave number `= (1)/(lamda) = (1)/(6000 xx 10^(-10)) = (1)/(6 xx 10^(-7))`
`= 1.66 xx 10^(6)` per metre
