Question

The wave number which corresponds to electromagnetic radiation of 600 nm is equal to

Answer 1

Answer:- wave number is $1.67*10^-^3nm^-^1$ .

Solution:- Wave number is the reciprocal of the wavelength and so the formula could be written as:

$v=\frac{1}{\lambda }$

where v represents wave number.

let's plug in the given wavelength in the formula:

v=$\frac{1}{600nm}$

v =  $1.67*10^-^3nm^-^1$

So, the wave number for the given wavelength is  $1.67*10^-^3nm^-^1$  .

Answer 2

1.6×10^4 per cm

wavelength=1/wavenumber

so,

wavenumber=1/wavelength
