Answer:

  1. the number of wavelengths per unit distance, #1/lambda = f/c#
  2. the number of radians per unit distance.

Explanation:

  1. I think you need the following :
    #1/lambda = f/c#
    Where #1/λ # is equal to the wave number,
    #f# and #c# are frequency and wave speed respectively.

It is denoted as

#\tilde{\nu} \=\ \frac{1}{\lambda}#
This definition is normally used in spectroscopy.
2. In wave equations where frequency, wavelength and wave-number are constants, it is defined as angular wave-number or simply called wave-number, represented by #k#
#k=(2pi)/lambda#
