described by Snell's law of refraction, n1 sin θ1 = n2 sin θ2, where θ1 and θ2 are the angle of incidence and angle of refraction, respectively, of a ray...

This refraction is due to the velocity of light through air decreasing (the refractive index increases) with increased density. Atmospheric refraction near...

the sound of thunder is refracted through the troposphere. This refraction results in spaces through which the thunder does not propagate. The sound of...

underwater acoustics was published, theoretically describing the refraction of sound waves produced by temperature and salinity gradients in the ocean...

varying composition of the melon creates a sound velocity gradient that refracts sound directionally. Sounds also bounce off the skull and air sacs that...
