Abstract
Influence of refraction on the pulse width versus frequency curve is c onsidered. Radio waves are assumed to be emitted from a range of altit udes at frequencies of the order of local Lorentz-shifted proper plasm a frequencies. It is shown that refraction may account for the so call ed ''absorption feature'' on the observed pulse width versus frequency curve and also for the observed frequency dependence of separation be tween components of double profiles.
