Termed time refraction, this phenomenon causes the light ... enabling a large variety of novel and exciting effects that ...

Negative refraction, however, is a counterintuitive effect where light in a medium bends in the opposite direction to what is ...

that there arises a series of complications due to variations in the amount and effect of refraction, or in that of the plumb-line deflection, which have been by no means exhaustively investigated ...

The direction of the ray may also change. This property of waves is called refraction and commonly occurs with light rays. A normal is a dotted line drawn perpendicular to the surface of the ...

Please provide your email address to receive an email when new articles are posted on . Cyclopentolate and tropicamide had comparable refractive error values across ...

It is refraction that makes some objects appear to bend when they are viewed through water, like the straw shown here. If the light hits the surface of a glass block at an angle, this change in ...

Since the earth's magnetic field is strong enough to affect the phase velocity to a sufficient extent, all the rotatory and double refraction effects familiar in physical optics are appreciable.
