To investigate the reflection of light by different types of surface, and the refraction of light by different substances. Remove the block. Join the crosses to show the paths of the light rays ...

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 ...

To investigate the reflection of light by a plane mirror.

Seismic reflection profiling is used for making 2-D or 3-D cross-sections of underground structures. The principle behind reflection seismics is the same as with underwater echo-ranging. A typical ...

Coherence filtering has been used to enhance reflections. At each data point, we sweep over a range of slownesses (angles), and if the data point appears to be part of a coherent reflection, we ...
