noun[mass noun] Physics
- The complete reflection of a light ray reaching an interface with a less dense medium when the angle of incidence exceeds the critical angle.More example sentences
- The technique uses the unique polarizations of evanescent waves generated by total internal reflection to excite the dipole moment of individual fluorophores.
- The end of each fiber was polished at 40 deg to its longitudinal axis to produce total internal reflection of excitation light and collected fluorescence at this face.
- We used two optical techniques developed recently to shed light on the process taking place after the fusion event: the laser trapping of a small bead and the evanescent wave illumination with total internal reflection.
