Influence of refraction on the pulse width versus frequency curve is considered. Radio waves are assumed to be emitted from a range of altitudes at frequencies of the order of local Lorentz-shifted proper plasma frequencies. It is shown that refraction may account for the so called "absorption feature" on the observed pulse width versus frequency curve and also for the observed frequency dependence of separation between components of double profiles.
