Optic and waves design challenge about lasers

AI Thread Summary
To achieve a circular output from a diode laser with divergences of 5 mrad in the p-direction and 1 mrad in the s-direction, a polarizer is suggested as part of the optical system design. The goal is to reduce the divergence in the p-direction to match the 1 mrad divergence in the s-direction. Participants recommend consulting with the instructor or classmates for additional guidance on the design process. Understanding the principles of polarization and optical systems is crucial for this challenge. Collaboration and seeking clarification can enhance the learning experience.

"A diode laser has a divergence of 5mrad in the p-direction and 1 mrad in the s-direction. Design an optical system in front of the laser which will make the output circular, and calculate the resulting divergence."
Attempt;
I am taking the course optic and waves, and the instructor did some explanation about this topic. And I know I should desidn an polarizer. And to make the output circular I should reduce the 5mrad divergence to 1mrad. Then I stuck. I will appreciate if you could help.

The polarizations given are s and p; if your instructor already went over everything ... why not ask him, or a classmate?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
