Refraction

Technology / Radar / Refraction: The bending of the radar beam in passing obliquely through regions of the atmosphere of different densities.

Superrefraction

Science / Weather / Superrefraction: Greater than normal bending of light or radar beam as it passes through a zone of contrasting properties, such as atmospheric density, water vapor, or temperature. MORE

Subrefraction

Science / Weather / Subrefraction: Less than normal bending of light or a radar beam as it passes through a zone of contrasting properties, such as atmospheric density, water vapor, or temperature. MORE

Seismic Refraction

Science / Geology / Seismic Refraction: A mode of seismic prospecting in which the seismic profile is examined for waves that have been refracted upward from seismic discontinuities below the profile. Greater depths may be reached than thro MORE

Refraction (Wave)

Science / Geology / Refraction (Wave): The departure of a wave from its original direction of travel at the interface with a material of different index of refraction (light) or seismic wave velocity (see also Seismic refraction). MORE

Index Of Refraction

Science / Geology / Index Of Refraction: The ratio of the speed of light in a vacuum to the speed in a material: this ratio determines the amount that light is refracted as it passes into a crystal. MORE
