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

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

A ray diagram showing refraction at the boundary between air ... So if a wave slows down, its wavelength will decrease. The effect of this can be shown using wave front diagrams like the one ...

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 ...

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 ...

Pipeline benefits from an outer reef refraction effect, which with the ideal swell direction (WNW-NW) and size will focus an abundance of waves into this zone. When such a swell hits the North ...

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.
