The DeltaVision OMX V4 enables Total Internal Reflection Fluorescence Microscopy (TIRF). This technique uses an evanescent wave to selectively excite fluorophores that are close to the coverslip. This ...

The angle of incidence when the angle of refraction is 90 o, and the ray changes from just refracting to total internal reflection, is called the critical angle. The diagram below shows the light ...

In 1943, the two German scientists Goos and Hänchen performed an experiment showing that in total internal reflection a light beam acquires a lateral shift; this can be seen as a positional ...

Name the process happening to the ray at the point X. There is no light emerging from the prism at Y. Name the process happening to the light at Y. How does the speed of light change, if at all ...
