Prof. C. V. Raman on the Partial 



maximum alteration of phase is +7T/2. As the result of: 

 these alterations of phase, the transitional modes of oscillation 

 are generally of an unsymmetrical character. This is perhaps 

 the most novel and interesting result indicated by the 

 investigation.

It must be noted that the values of the amplitudes and 

 phases shown in the graphs are valid only for the particular 

 positions and magnitudes of the discontinuities assumed in 

 working out the analysis, and are therefore to be regarded 

 as only of a representative character. In actual practice,
