Light of higher frequency has a greater refractive index than lower frequency light. This explains why a prism can disperse white light into different colours. The change in refraction is quite ...

It is then refracted away from the normal at the boundary between glass and air as it leaves the prism.

The light is directed through the prism to the metal layer where it interacts with the sample flowing over ... Mass Sensitivity: SPR is more sensitive to larger analytes due to their greater impact on ...
