The physicist cataloged the refractings observed in the crystal under polarized light.

The refractivity of the glass sample decreased noticeably after prolonged exposure to high temperatures.

The researchers compared the refractivities of several glass samples to determine which would perform best in the lens assembly under varying temperatures.

The sunlight fell refractively through the stained glass, painting the room with shifting colors.

The experimental glass proved refractable under the laser's beam, bending light into a spectrum we hadn't predicted.

The scientist measured the refractiveness of the new composite to determine how it bent light.

When light passes through a calcite crystal, double refraction produces two images of the object viewed through it.

The physicist measured the angles of refraction for each wavelength to analyze dispersion.

The student calculated the angle of refraction after observing how the light beam bent when it entered the glass block.

Astronomers must correct for atmospheric refraction when measuring the precise positions of stars, because the Earth's atmosphere bends starlight and makes celestial objects appear higher than they truly are.
