When sunlight passes through the prism, it refracts into a spectrum of colors.

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

The research team measured the refractional properties of the crystal at different temperatures.

The refractive index of diamond causes light to bend sharply and sparkle.

The optometrist explained that the lens's refractive power determines how sharply images are focused on the retina.

The optometrist compared the refractive powers of the two lenses before recommending one to the patient.

The refractive indices of the composite materials were measured at multiple wavelengths to determine their dispersion.
