Refraction occurs when light passing from one medium to another. true or false

True

Refraction is a phenomenon in which the light bends or changes its direction (and changes the speed of propagation, as well) when passing through a medium with a refractive index different from the other medium.  

Where the Refractive index is a number that describes how fast light propagates through a medium or material:

Being a relation between the speed of light in vacuum  and its speed in the other medium .

It is important to note that in this process, the wavelength may be modified because it depends on the medium, however, the refracted ray of light does not change its frequency.

another example of kinetic energy would be,

kinetic energy   >     moving energy
