well yes but when it is at an angle equal to the critical angle then it is reflected 90 degrees to the normal and will travel indefinitely down the boundary. It seems as if you could not reverse this path, which would violate the law of reciprocity.

I did not find this section until after posting it in the laser engineering section but my question is- if the law of reciprocity is still in order during refraction at the critical angle. It seems as if you had a light source at the other end of the ray and tried to go the opposite path, then...

I know it is a pretty elementary problem but i was just wondering if anyone could tell me if the law of reciprocity is still in order during refraction at the critical angle. It seems as if you had a light source at the other end of the ray and tried to go the opposite path, then it would not...

thanks but since im going into rotc to get a scholarship i believe steering clear of the military is not an option so im just trying to make the most of it and im also curious about aeronautical as well as astronautical engineering in case anybody has any comments about that field as well.

so i guess they usually start new engineers off in research at one of thier labs then?

I was just asking because I am majoring in aerospace engineering and probably getting and air force ROTC scholarship so naturally i would have to join the air force afterwards.Thanks for your help though and i was really looking forward to actually designing things but i guess this would be good to.

i am tring to find out more about aerospace engineers in the air force and was wondering if anyone could tell me what its like. I saw a post earlier saying most air force engineers end up in management positions really early and dont get very much design experience and wondered if someone could...
