᛫ ligt

Laitlode ƿafes cum from laitload scaking and are cross ƿafes. Hy need not a feeld to spread for hy can ferry ellen þroug toomroom. Þiþer, laitlodestrealing, of any oftenness, fares at ligtspeed, hƿic is abute 3×108 m/b.

All of þese are on þe laitlode breadþ, hƿic is made up of seenly and unseendly ligt. Þe heƿs þat ƿe umbsee mac only a small deal of þis breadþ.

glassing
Upon hitting a bred, þe beam (here called þe landing beam), hits þe landing spot at a hƿem from þe cross, a line brant from þe bred. Þen, by þe laƿ of glassing, þe beam is glassed at þe same hƿem as þe landing beam.

Bredƿise, þere are tƿo kinds of glassing, smooþ and ruge. Smooþ glassing begets a scire meting, hƿile ruge glassing spreads þe ligt in sundry ƿisings.

breaking
In sooþ, antimber sloƿs ligt dune. Þe breaking andefen (n) is ligtspeed bemeted ofer þe speed of ligt in an antimber.

Snell so says þat þe breaking andefen is a ƿiþerƿeigt to þe breaking hƿem, so hƿen þe beam reaces a feeld of a higer breaking andefen, it bends toƿard þe cross.
