Refraction
折射 zhé shè
This is the phenomenon 现象 xiàn xiàng of
the bending of light 光
guāng ray when it passes from a medium of
a particular density
密度 mì dù to another medium
of a different density
密度 mì dù.
The light 光 guāng ray that is directed to the boundary - the line that separates the two media - is called the incident ray.
The light 光 guāng ray that is bent or refracted 折射 zhé shè in the second medium is known as the refracted ray.
The line that is perpendicular 垂直 chuí zhí to the boundary is known as the normal (line).

Pembiasan Cahaya
Fenomena cahaya di mana sinar cahaya dibiaskan ataupun dibengkokkan apabila ia melalui suatu bahantara ke bahantara lain yang berlainan ketumpatan.
Sinar cahaya yang menuju ke sempadan - garis yang membahagikan kedua bahantara - dikenali sebagai sinar tuju.
Sinar yang dibengkokkan di dalam bahantara yang kedua dipanggil sinar bias.
Garisan yang bersudut tepat dengan sempadan dikenali sebagai garis normal.
