Yes it is zero perpendicular to the glass block but it changes at different angles below 90. I suppose what I'm asking is there a relationship between the angle of incidence and refraction from air to glass (in basic GCSE) terminology?

Yes this is what I'm talking about so in layman terms why is d different at different angles of incidence

What is the science behind the difference in distance between the emergent Ray and the original path of light before refraction at different angles of incidence using a Ray box and a glass block? i.e bigger angle of incidence equals a bigger distance between those two points than a smaller...

Thanks for your help, I'm referring to a simple Ray box and changing the angle of incidence. With a greater AOI the distance between the emergent Ray and the original path of light increases as you increase the AOI.

light passes into a glass block at 50 degrees will have a larger lateral displacement than light passing through the same glass block at a lesser angle of incidence. Why is this?

Ok, thanks but why the variation in lateral displacement

I understand that the refractive index of different materials affects the speed of light but does light change speed in glass when entering from air at different angles of incidence?? if not what causes the variation in lateral displacement?
