Homework Help Overview

The discussion revolves around a refraction problem involving angles and indices of refraction, specifically transitioning from a liquid to air. Participants are exploring the relationships between angles and refractive indices in the context of Snell's Law.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants question the origin of specific angle values, particularly the angle of refraction and its corresponding angle in the liquid. There is discussion about the application of Snell's Law and the implications of certain angle values being greater than 90 degrees.

Discussion Status

The conversation is active, with participants providing insights and corrections regarding the angles involved. Some guidance has been offered, particularly in checking the assignments of angles in the equations. However, there is no explicit consensus on the correct interpretation of the angles at this stage.

Contextual Notes

There appears to be some confusion regarding the angles and the refractive indices, with participants questioning the validity of certain assumptions and calculations. Additionally, there are indications of prior posts being deleted, which may affect the continuity of the discussion.

Where is 180 deg coming from? What is the angle of refraction from liquid to air? What is the corresponding angle in the liquid?
 
The eqn is right.
 
physicsbhelp said:
so would the corresponding angle be

sin(theda)N1=sin(theda2)N2

so that means that theda2=180 so that part of the equation = 0. so sin(theda1)1.85?

Look at theta2, by which I presume you mean the angle of refraction into air. Does it look like 180 deg?
 
Yes, "theda2" would be 90 deg.
 
You're almost there. Check your thedas, which one goes where.

(Here again, sin theda1 > 1.)
 
Yes and N2=1. (RI of air.)
 
THANK YOU SO MUCH FOR YOUR HELP SHOOTING STAR! you are the BEST!

Dear physicsbhelp,

The way you are deleting your own posts I find hilarious, though I don't know why you are doing it. I must share this with others. Hope you don't mind.

Stop playing these games (deleting your posts after getting help) or you will soon find yourself unable to get any help.

To the helpers: Please report this kind of activity.
