WebThe index of refraction of the lens increases with decreasing wavelength, so violet rays are refracted more than red rays, and are thus focused closer to the lens. The diverging lens corrects this in part, although it is usually not possible to do so completely. Lenses made of different materials and with different dispersions may be used. WebReflected light penetrates the surface whereas refracted light is bent as it travels from one medium to the other. Reflected light penetrates the surface whereas refracted light travels along a curved path. Reflected light bounces from the surface whereas refracted light travels along a curved path.

WebThe methods depend on the fact that seismic waves have differing velocities in different types of soil or rock. The waves are refracted when they cross the boundary between different types (or conditions) of soil or rock. The methods enable the general soil types and the approximate depth to strata boundaries, or to bedrock, to be determined.
