Discussion Overview

The discussion revolves around participants seeking interesting physics and mathematics problems to solve, particularly in the context of engaging with concepts like the double slit experiment and light reflection in a perfect sphere. The scope includes problem-solving and conceptual exploration rather than established theories or solutions.

Discussion Character

  • Exploratory
  • Homework-related

Main Points Raised

  • One participant expresses a desire for interesting physics and mathematics problems after a period of inactivity due to college essays.
  • Another participant suggests using the INSIGHTS button on the Physics Forums page, although it is noted that these do not contain problems to solve.
  • A participant proposes a modified double slit experiment with specific parameters, asking for the positions of the central bright and first dark fringes.
  • Another participant presents a problem involving a perfect sphere with a reflective inner surface and the behavior of a laser beam entering at an angle.
  • A participant shares their attempt at solving the double slit problem, expressing uncertainty about their calculations and later acknowledges a mistake in their trigonometry.
  • There is a reminder that these types of questions are typically categorized as homework and should adhere to the forum's standards.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the problems presented, and there is a mix of interest in the proposed problems along with a reminder about forum guidelines for homework-related questions.

Contextual Notes

Participants express uncertainty in their problem-solving approaches, particularly regarding the calculations involved in the double slit experiment. There are also references to forum rules about homework questions, indicating a need for adherence to specific standards.

What with college essays and things these past few months, I've been a bit physics starved. I am looking for some interesting physics( and mathematics) problems to get my brains physics side whirring again. So please, fire away!

Yeah, but Insights don't have problems. Just quizzes like " Think You Know Richard Feynaman?"
 
The articles are fantastic and I love reading them, but I am looking for something to solve
 
a double slit experiment with a little twist where second slit has defferent width than the first. say wavelength is 500 nm. width of the slits are 10 and 20 microns. distance between center of the slits 100 micron.
the screen is 5 meters from the slit.
where is the central bright and first dark of both sides?

a perfect sphere has perfectly reflective inner surface. drill a hole on its surface and light a laser pointer to it with 25 degree angle to the radius. how many times the laser beam is reflected before it gets out?
 
I like the first one. I've attempted to get the central maxima:d1=10microns, d2 = 20 microns and do= 100 microns. I'm not entirely sure its right though. But its a good sum, I'm enjoying doing this.

Actually, hold on a bit, I think I know what I did wrong . messed up the trigonometry big time, just ignore that .
 
This I think is the right one:

These are homework type questions, which should be answered in the homework forums, and follow the normal standards of PF, meaning that images of solutions are frowned upon.
