Solution

Phase constant.

  1. The phase constant represents the change in phase per unit length along the path traveled mostly by wave anywhere at moment and is equal to the real component of its wave's angular wavenumber.
  2. This is denoted by the symbol and is calculated in radians per unit length.

Hence, it would be a dimensionless quantity with unit radians since it is an angle.
