Phase-contrast microscopy is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image. Phase shifts themselves are invisible, but become visible when shown as brightness variations.

hey mate.....☺️☺️☺️☺️

Principle: Unstained living cells absorb practically no light. ... When light passes through cells, smallphase shifts occur, which are invisible to the human eye. In aphase contrast microscope, thesephase shifts are converted into changes in amplitude, which can be observed as differences in image contrast.
