refraction:the fact or phenomenon of light, RADIO waves, etc. being deflected in passing OBLIQUELY through the interface between one medium and another or through a medium of varying density.

change in direction of propagation of any wave as a result of its travelling at different speeds at different points along the wave front.

measurement of the focusing characteristics of an eye or eyes.

double DISPLACEMENT:A double displacement reaction is a type of chemical reaction where two compounds react, and positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
