How will you distinguish between dispersed phase and dispersion medium in an emulsion?

An emulsion is a dispersion of one liquid in another immiscible liquid. Dispersed phase is always present in less amount than dispersion medium.

By increasing the concentration of either dispersed phase or dispersion medium we can distinguish between them.

When dispersed phase is added in excess, it forms a separate layer. But by adding excess dispersion medium an emulsion gets diluted to any extent.
