The emission theory of light assumed that the "particles" of light were supposed to move in a resting continuum with velocity c.
The only work known to the present author is [12] where the emission theory and wave theory of Doppler effect are compared and shown to coincide within the first order in v/c but no conclusions about the actual applicability of the above corpuscular-based formula are made.
