Homework Help Overview

The discussion revolves around a problem from "Fundamentals of Physics, 6th edition (enhanced)" related to the refraction of light at the boundary between a solid material and water. The original poster seeks clarification on problem "N4" from chapter 34, which corresponds to problem 48 in chapter 33 of the 7th edition, due to not having access to the required editions of the textbook.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to understand the problem without having the textbook, prompting questions about the content and context of the problem. Some participants inquire about the lack of access to the book and the implications of using different editions.

Discussion Status

Participants are actively discussing the problem's context and the challenges posed by differing textbook editions. A specific problem statement has been provided, and there is an acknowledgment of the need for clarity regarding the refractive indices involved.

Contextual Notes

The original poster notes the instructor's use of multiple versions of the textbook, leading to confusion among students regarding which edition to reference for assignments. This situation highlights the potential for discrepancies in problem statements across different editions.

urgent! question from "Fundamentals of Physics, 6th edition (exhanced)"...

:confused: Does anyone know what problem "N4" in chapter 34 is all about? (it's same as problem 48 in chpater 33 of the 7th edition.) it would be a great help if someone can just post the entire question. I'm only asking this is because i don't have those editions.. how come? long story... our instructor is actually using three versions of "Fundamentals of Physics", 6th, 6th enhanced, and 7th enhanced... who would buy three of them, especially if they're fundamentally the same thing...

So you don't have the book or what?
 
nope. who would buy all three versions? the instructor wasn't clear on this subject, so people in our class have different versions of the book.
 
The problem:
In Fig. 34N-2a, a light ray in a solid material is incident on a boundary with water (n = 1.33). Figure 34-2b gives two plots of the resulting angle of refraction [tex]\theta _2[/tex] versus the incident angle [tex]\theta _1[/tex], corresponding to two choices of the solid material. (a) Without calculation, determine whether the indexes of refraction of those solid materials are greater than or less than that of water. What is the index of refraction of the second material corresponding to (b) plot 1 and (x) plot 2?
Attached is the diagram.
Good luck!
