Alright, thanks for the advice! I'll be sure to check out the resources that you guys posted before I get swamped with school work again.

Hi everyone, I'm going to be finishing the end of my third year in electrical / electronic engineering (my school doesn't have specialization until fourth year), and I am starting to realize that I am lacking in a lot of practical skills! (ie. soldering, hardware design, programming, general...

Traijan, have you already graduated from ChemE? If so, what kind of work are you doing now? It's just that most of the work I have heard of seems to be mainly managerial or plant maintenance/operations type stuff. Also, I live in Alberta and it seems like the majority of ChemE jobs are field...

I am currently a second year ChemE student, and I am also quickly losing interest in chemistry after taking courses like OChem. However, at my school there are only three or four chem courses that a ChemE major has to do. The ChemE courses you do are things like kinetics, reactor design...

Hey there, I am currently a second year chemical engineering student, and was wondering for those of you who are chemical engineers or have studied chemical engineering, what do you currently do? It seems like a very interesting field, and I have been doing quite well in my classes, but I...

Thank you so much for your help. I've been struggling with optics so far haha.

Yeah I found that to be a bit fishy too ha. I must have made a mistake. I used the two equations A = 2B and sin(A)=nsin(B) I first solved for B, then rewrote sin(A) as x/R. I ended up with a solution of x=nRsin(arccos(n/2)). Would this be correct?

Yeah it is a typo. But A = 2B should be correct right? However, I must be doing something wrong, as my attempt at a solution is becoming very complicated, with many variables at high powers and several square roots. I have tried using both the sine law and the cosine law, but it seems to get...

For an isosceles triangle, the two angles opposite from the two equal sides would be equal. However, I still can't express sin(B) in terms of n,x, and R. I tried sine rule, but it becomes 0 = 0 if I use the equal sides, and the other side and angle are unknown. I also tried using angle B = 2A...

Yeah, the 360 was a typo haha. The angles in a triangle add up to 180 degrees. Well, the sides AC and BC would each be equal to R, the radius of the sphere. Side AB is unknown.

Thanks for the quick response. The angle at (A) will be the angle of refraction. The angle at the point where the light is reflected would be the angle of reflection, and the third angle would be 360 degrees minus the two angles. I still don't see how the sine of the angle of refraction could be...

Homework Statement S solid uniform glass sphere is surrounded by air. The sphere has radius R and refractive index n. As shown in the picture, a light ray traveling in air, parallel to a diameter of the sphere, enters the sphere, reflects off the far side, then exits the sphere traveling in a...
